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.
This rule disallows
Examples of incorrect code for this rule:
/*eslint no-array-constructor: "error"*/ Array(0, 1, 2) new Array(0, 1, 2)
Examples of correct code for this rule:
/*eslint no-array-constructor: "error"*/ Array(500) new Array(someOtherArray.length) [0, 1, 2]
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.
This rule was introduced in ESLint 0.4.0.
