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 132.

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.

enforce consistent spacing before and after keywords (keyword-spacing)

(fixable) The --fix option on the [command line](../user-guide/command-line-interface#fix) automatically fixes problems reported by this rule.

Keywords are syntax elements of JavaScript, such as function and if. These identifiers have special meaning to the language and so often appear in a different color in code editors. As an important part of the language, style guides often refer to the spacing that should be used around keywords. For example, you might have a style guide that says keywords should be always surrounded by spaces, which would mean if-else statements must look like this:

if (foo) {
    // ...
} else {
    // ...
}

Of course, you could also have a style guide that disallows spaces around keywords.

Rule Details

This rule enforces consistent spacing around keywords and keyword-like tokens: as (in module declarations), break, case, catch, class, const, continue, debugger, default, delete, do, else, export, extends, finally, for, from (in module declarations), function, get (of getters), if, import, in, instanceof, let, new, of (in for-of statements), return, set (of setters), static, super, switch, this, throw, try, typeof, var, void, while, with, and yield. This rule is designed carefully not to conflict with other spacing rules: it does not apply to spacing where other rules report problems.

Options

This rule has an object option:

• "before": true (default) requires at least one space before keywords
• "before": false disallows spaces before keywords
• "after": true (default) requires at least one space after keywords
• "after": false disallows spaces after keywords
• "overrides" allows overriding spacing style for specified keywords

before

Examples of incorrect code for this rule with the default { "before": true } option:

/*eslint keyword-spacing: ["error", { "before": true }]*/

if (foo) {
    //...
}else if (bar) {
    //...
}else {
    //...
}

Examples of correct code for this rule with the default { "before": true } option:

/*eslint keyword-spacing: ["error", { "before": true }]*/
/*eslint-env es6*/

if (foo) {
    //...
} else if (bar) {
    //...
} else {
    //...
}

// no conflict with `array-bracket-spacing`
let a = [this];
let b = [function() {}];

// no conflict with `arrow-spacing`
let a = ()=> this.foo;

// no conflict with `block-spacing`
{function foo() {}}

// no conflict with `comma-spacing`

When Not To Use It

If you don't want to enforce consistency on keyword spacing, then it's safe to disable this rule. Source: http://eslint.org/docs/rules/

Disallow Undeclared Variables (no-undef)

This rule can help you locate potential ReferenceErrors resulting from misspellings of variable and parameter names, or accidental implicit globals (for example, from forgetting the var keyword in a for loop initializer).

Rule Details

Any reference to an undeclared variable causes a warning, unless the variable is explicitly mentioned in a /*global ...*/ comment.

Examples of incorrect code for this rule:

/*eslint no-undef: "error"*/

var a = someFunction();
b = 10;

Examples of correct code for this rule with global declaration:

/*global someFunction b:true*/
/*eslint no-undef: "error"*/

var a = someFunction();
b = 10;

The b:true syntax in /*global */ indicates that assignment to b is correct.

Examples of incorrect code for this rule with global declaration:

/*global b*/
/*eslint no-undef: "error"*/

b = 10;

By default, variables declared in /*global */ are read-only, therefore assignment is incorrect.

Options

• typeof set to true will warn for variables used inside typeof check (Default false).

typeof

Examples of correct code for the default { "typeof": false } option:

/*eslint no-undef: "error"*/

if (typeof UndefinedIdentifier === "undefined") {
    // do something ...
}

You can use this option if you want to prevent typeof check on a variable which has not been declared.

Examples of incorrect code for the { "typeof": true } option:

/*eslint no-undef: ["error", { "typeof": true }] */

if(typeof a === "string"){}

Examples of correct code for the { "typeof": true } option with global declaration:

/*global a*/
/*eslint no-undef: ["error", { "typeof": true }] */

if(typeof a === "string"){}

Environments

For convenience, ESLint provides shortcuts that pre-define global variables exposed by popular libraries and runtime environments. This rule supports these environments, as listed in Specifying Environments. A few examples are given below.

browser

Examples of correct code for this rule with browser environment:

/*eslint no-undef: "error"*/
/*eslint-env browser*/

setTimeout(function() {
    alert("Hello");
});

node

Examples of correct code for this rule with node environment:

/*eslint no-undef: "error"*/
/*eslint-env node*/

var fs = require("fs");
module.exports = function() {
    console.log(fs);
};

When Not To Use It

If explicit declaration of global variables is not to your taste.

Compatibility

This rule provides compatibility with treatment of global variables in JSHint and JSLint.
