      Duplicated Code

      Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:

      Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

      When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

      Tuning

      This issue has a mass of 50.

      We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.

      The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

      If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

      See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.

                    You can immediately invoke function expressions, but not function declarations. A common technique to create an immediately-invoked function expression (IIFE) is to wrap a function declaration in parentheses. The opening parentheses causes the contained function to be parsed as an expression, rather than a declaration.

                    // function expression could be unwrapped
                    var x = function () { return { y: 1 };}();

                    Rule Details

                    This rule requires all immediately-invoked function expressions to be wrapped in parentheses.

                    Options

                    This rule has two options, a string option and an object option.

                    String option:

                    • "outside" enforces always wrapping the call expression. The default is "outside".
                    • "inside" enforces always wrapping the function expression.
                    • "any" enforces always wrapping, but allows either style.

                    Object option:

                    • "functionPrototypeMethods": true additionally enforces wrapping function expressions invoked using .call and .apply. The default is false.

                    outside

                    Examples of incorrect code for the default "outside" option:

                    /*eslint wrap-iife: ["error", "outside"]*/
                    
                    var x = function () { return { y: 1 };}(); // unwrapped
                    var x = (function () { return { y: 1 };})(); // wrapped function expression

                    Examples of correct code for the default "outside" option:

                    /*eslint wrap-iife: ["error", "outside"]*/
                    
                    var x = (function () { return { y: 1 };}()); // wrapped call expression

                    inside

                    Examples of incorrect code for the "inside" option:

                    /*eslint wrap-iife: ["error", "inside"]*/
                    
                    var x = function () { return { y: 1 };}(); // unwrapped
                    var x = (function () { return { y: 1 };}()); // wrapped call expression

                    Examples of correct code for the "inside" option:

                    /*eslint wrap-iife: ["error", "inside"]*/
                    
                    var x = (function () { return { y: 1 };})(); // wrapped function expression

                    any

                    Examples of incorrect code for the "any" option:

                    /*eslint wrap-iife: ["error", "any"]*/
                    
                    var x = function () { return { y: 1 };}(); // unwrapped

                    Examples of correct code for the "any" option:

                    var x = (function () { return { y: 1 };})(); // wrapped function expression

                    functionPrototypeMethods

                    Examples of incorrect code for this rule with the "inside", { "functionPrototypeMethods": true } options:

                    Object option:

                    • "functionPrototypeMethods": true additionally enforces wrapping function expressions invoked using .call and .apply. The default is false.

                    Require === and !== (eqeqeq)

                    It is considered good practice to use the type-safe equality operators === and !== instead of their regular counterparts == and !=.

                    The reason for this is that == and != do type coercion which follows the rather obscure Abstract Equality Comparison Algorithm. For instance, the following statements are all considered true:

                    • [] == false
                    • [] == ![]
                    • 3 == "03"

                    If one of those occurs in an innocent-looking statement such as a == b the actual problem is very difficult to spot.

                    Rule Details

                    This rule is aimed at eliminating the type-unsafe equality operators.

                    Examples of incorrect code for this rule:

                    /*eslint eqeqeq: "error"*/
                    
                    if (x == 42) { }
                    
                    if ("" == text) { }
                    
                    if (obj.getStuff() != undefined) { }

                    The --fix option on the command line automatically fixes some problems reported by this rule. A problem is only fixed if one of the operands is a typeof expression, or if both operands are literals with the same type.

                    Options

                    always

                    The "always" option (default) enforces the use of === and !== in every situation (except when you opt-in to more specific handling of null [see below]).

                    Examples of incorrect code for the "always" option:

                    /*eslint eqeqeq: ["error", "always"]*/
                    
                    a == b
                    foo == true
                    bananas != 1
                    value == undefined
                    typeof foo == 'undefined'
                    'hello' != 'world'
                    0 == 0
                    true == true
                    foo == null

                    Examples of correct code for the "always" option:

                    /*eslint eqeqeq: ["error", "always"]*/
                    
                    a === b
                    foo === true
                    bananas !== 1
                    value === undefined
                    typeof foo === 'undefined'
                    'hello' !== 'world'
                    0 === 0
                    true === true
                    foo === null

                    This rule optionally takes a second argument, which should be an object with the following supported properties:

                    • "null": Customize how this rule treats null literals. Possible values:
                      • always (default) - Always use === or !==.
                      • never - Never use === or !== with null.
                      • ignore - Do not apply this rule to null.

                    smart

                    The "smart" option enforces the use of === and !== except for these cases:

                    • Comparing two literal values
                    • Evaluating the value of typeof
                    • Comparing against null

                    Examples of incorrect code for the "smart" option:

                    /*eslint eqeqeq: ["error", "smart"]*/
                    
                    // comparing two variables requires ===
                    a == b
                    
                    // only one side is a literal
                    foo == true
                    bananas != 1
                    
                    // comparing to undefined requires ===
                    value == undefined

                    Examples of correct code for the "smart" option:

                    /*eslint eqeqeq: ["error", "smart"]*/
                    
                    typeof foo == 'undefined'
                    'hello' != 'world'
                    0 == 0
                    true == true
                    foo == null

                    allow-null

                    Deprecated: Instead of using this option use "always" and pass a "null" option property with value "ignore". This will tell eslint to always enforce strict equality except when comparing with the null literal.

                    ["error", "always", {"null": "ignore"}]

                    When Not To Use It

                    If you don't want to enforce a style for using equality operators, then it's safe to disable this rule. Source: http://eslint.org/docs/rules/

                    Require IIFEs to be Wrapped (wrap-iife)

                    You can immediately invoke function expressions, but not function declarations. A common technique to create an immediately-invoked function expression (IIFE) is to wrap a function declaration in parentheses. The opening parentheses causes the contained function to be parsed as an expression, rather than a declaration.

                    // function expression could be unwrapped
                    var x = function () { return { y: 1 };}();
                    
                    // function declaration must be wrapped
                    function () { /* side effects */ }(); // SyntaxError

                    This rule requires all immediately-invoked function expressions to be wrapped in parentheses.

                    Options

                    This rule has two options, a string option and an object option.

                    String option:

                    • "outside" enforces always wrapping the call expression. The default is "outside".
                    • "inside" enforces always wrapping the function expression.
                    • "any" enforces always wrapping, but allows either style.

                    Object option:

                    • "functionPrototypeMethods": true additionally enforces wrapping function expressions invoked using .call and .apply. The default is false.

                    /*eslint eqeqeq: ["error", "smart"]*/
                    
                    typeof foo == 'undefined'
                    'hello' != 'world'
                    0 == 0
                    true == true
                    foo == null

                    allow-null

                    Deprecated: Instead of using this option use "always" and pass a "null" option property with value "ignore". This will tell eslint to always enforce strict equality except when comparing with the null literal.

                    ["error", "always", {"null": "ignore"}]

                    When Not To Use It

                    If you don't want to enforce a style for using equality operators, then it's safe to disable this rule. Source: http://eslint.org/docs/rules/

                    Require IIFEs to be Wrapped (wrap-iife)

                    You can immediately invoke function expressions, but not function declarations. A common technique to create an immediately-invoked function expression (IIFE) is to wrap a function declaration in parentheses. The opening parentheses causes the contained function to be parsed as an expression, rather than a declaration.

                    // function expression could be unwrapped
                    var x = function () { return { y: 1 };}();
                    
                    // function declaration must be wrapped
                    function () { /* side effects */ }(); // SyntaxError

                    Rule Details

                    This rule requires all immediately-invoked function expressions to be wrapped in parentheses.

                    Options

                    This rule has two options, a string option and an object option.

                    String option:

                    • "outside" enforces always wrapping the call expression. The default is "outside".
                    • "inside" enforces always wrapping the function expression.
                    • "any" enforces always wrapping, but allows either style.

                    Object option:

                    • "functionPrototypeMethods": true additionally enforces wrapping function expressions invoked using .call and .apply. The default is false.

                    outside

                    Examples of incorrect code for the default "outside" option:

                    /*eslint wrap-iife: ["error", "outside"]*/
                    
                    var x = function () { return { y: 1 };}(); // unwrapped
                    var x = (function () { return { y: 1 };})(); // wrapped function expression

                    Examples of correct code for the default "outside" option:

                    /*eslint wrap-iife: ["error", "outside"]*/
                    
                    var x = (function () { return { y: 1 };}()); // wrapped call expression

                    inside

                    Examples of incorrect code for the "inside" option:

                    /*eslint wrap-iife: ["error", "inside"]*/
                    
                    var x = function () { return { y: 1 };}(); // unwrapped
                    var x = (function () { return { y: 1 };}()); // wrapped call expression

                    Examples of correct code for the "inside" option:

                    /*eslint wrap-iife: ["error", "inside"]*/
                    
                    var x = (function () { return { y: 1 };})(); // wrapped function expression

                    any

                    Examples of incorrect code for the "any" option:

                    /*eslint wrap-iife: ["error", "any"]*/
                    
                    var x = function () { return { y: 1 };}(); // unwrapped

                    Examples of correct code for the "any" option:

                    /*eslint wrap-iife: ["error", "any"]*/
                    
                    var x = (function () { return { y: 1 };}()); // wrapped call expression
                    var x = (function () { return { y: 1 };})(); // wrapped function expression

                    functionPrototypeMethods

                    Examples of incorrect code for this rule with the "inside", { "functionPrototypeMethods": true } options:

                    /* eslint wrap-iife: [2, "inside", { functionPrototypeMethods: true }] */
                    
                    var x = function(){ foo(); }()
                    var x = (function(){ foo(); }())
                    var x = function(){ foo(); }.call(bar)
                    var x = (function(){ foo(); }.call(bar))

                    Examples of correct code for this rule with the "inside", { "functionPrototypeMethods": true } options:

                    /* eslint wrap-iife: [2, "inside", { functionPrototypeMethods: true }] */
                    
                    var x = (function(){ foo(); })()
                    var x = (function(){ foo(); }).call(bar)
