    Severity: Minor

    Rule: no-var-keyword

    Disallows usage of the var keyword.

    Use let or const instead.

    Rationale

    Declaring variables using var has several edge case behaviors that make var unsuitable for modern code. Variables declared by var have their parent function block as their scope, ignoring other control flow statements. vars have declaration "hoisting" (similar to functions) and can appear to be used before declaration.

    Variables declared by const and let instead have as their scope the block in which they are defined, and are not allowed to used before declaration or be re-declared with another const or let.

    An optional object containing the property "destructuring" with two possible values:

    • "any" (default) - If any variable in destructuring can be const, this rule warns for those variables.
    • "all" - Only warns if all variables in destructuring can be const.

    Rule: prefer-object-spread

    Shadowed name: 'Unit'
    Open

            var Unit = this.get(unitType);
    Severity: Minor
    Found in src/units-registry.ts by tslint

    Rule: no-shadowed-variable

    Disallows shadowing variable declarations.

    Rationale

    When a variable in a local scope and a variable in the containing scope have the same name, shadowing occurs. Shadowing makes it impossible to access the variable in the containing scope and obscures to what value an identifier actually refers. Compare the following snippets:

    const a = 'no shadow';
function print() {
    console.log(a);
}
print(); // logs 'no shadow'.
    const a = 'no shadow';
function print() {
    const a = 'shadow'; // TSLint will complain here.
    console.log(a);
}
print(); // logs 'shadow'.

    ESLint has an equivalent rule. For more background information, refer to this MDN closure doc.

    Config

    You can optionally pass an object to disable checking for certain kinds of declarations. Possible keys are "class", "enum", "function", "import", "interface", "namespace", "typeAlias" and "typeParameter". You can also pass "underscore" to ignore variable names that begin with _. Just set the value to false for the check you want to disable. All checks default to true, i.e. are enabled by default. Note that you cannot disable variables and parameters.

    The option "temporalDeadZone" defaults to true which shows errors when shadowing block scoped declarations in their temporal dead zone. When set to false parameters, classes, enums and variables declared with let or const are not considered shadowed if the shadowing occurs within their temporal dead zone.

    The following example shows how the "temporalDeadZone" option changes the linting result:

    function fn(value) {
    if (value) {
        const tmp = value; // no error on this line if "temporalDeadZone" is false
        return tmp;
    }
    let tmp = undefined;
    if (!value) {
        const tmp = value; // this line always contains an error
        return tmp;
    }
}
