unicorn/no-new-array Correctness

✅ This rule is turned on by default.

🚧 An auto-fix is still under development.

Disallow new Array().

When using the Array constructor with one argument, it's not clear whether the argument is meant to be the length of the array or the only element.

Examples of incorrect code for this rule:

javascript

const array = new Array(1);
const array = new Array(42);
const array = new Array(foo);

Examples of correct code for this rule:

javascript

const array = Array.from({ length: 42 });
const array = [42];

How to use

  "rules": {
