@typescript-eslint/no-array-constructor

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.

On by default as a warning. To turn it off:

[lint.rules]
"@typescript-eslint/no-array-constructor" = "off" # or "error"

Examples#

const sizes = new Array(10, 20, 30);
const names = Array();

const sizes = [10, 20, 30];
const names: string[] = [];

const slots = new Array(5);
const labels = new Array<string>();
