# disallow `Array` constructors (no-array-constructor)
|
|
|
|
Use of the `Array` constructor to construct a new array is generally
|
|
discouraged in favor of array literal notation because of the single-argument
|
|
pitfall and because the `Array` global may be redefined. The exception is when
|
|
the Array constructor is used to intentionally create sparse arrays of a
|
|
specified size by giving the constructor a single numeric argument.
|
|
|
|
## Rule Details
|
|
|
|
This rule disallows `Array` constructors.
|
|
|
|
Examples of **incorrect** code for this rule:
|
|
|
|
```js
|
|
/*eslint no-array-constructor: "error"*/
|
|
|
|
Array(0, 1, 2)
|
|
```
|
|
|
|
```js
|
|
/*eslint no-array-constructor: "error"*/
|
|
|
|
new Array(0, 1, 2)
|
|
```
|
|
|
|
Examples of **correct** code for this rule:
|
|
|
|
```js
|
|
/*eslint no-array-constructor: "error"*/
|
|
|
|
Array(500)
|
|
```
|
|
|
|
```js
|
|
/*eslint no-array-constructor: "error"*/
|
|
|
|
new Array(someOtherArray.length)
|
|
```
|
|
|
|
## When Not To Use It
|
|
|
|
This rule enforces a nearly universal stylistic concern. That being said, this
|
|
rule may be disabled if the constructor style is preferred.
