# @typescript-eslint/no-array-constructor

> Disallow `Array()` and `new Array()` in favor of array literals

`new Array(1, 2)` makes `[1, 2]`, but `new Array(2)` makes an empty array of length 2. An array literal always holds what you write in it.

A call with exactly one argument is allowed, because that's how you make an array of a given length. A call with a type argument, such as `new Array<string>()`, is allowed too.

It's the TypeScript version of `no-array-constructor`.

`--fix` rewrites the call as an array literal.

This rule is on by default in TypeScript files.
