oxc/uninvoked-array-callback Correctness ​

✅ This rule is turned on by default.

What it does ​

This rule applies when an Array function has a callback argument used for an array with empty slots.

Why is this bad? ​

When the Array constructor is called with a single number argument, an array with the specified number of empty slots (not actual undefined values) is constructed. If a callback function is passed to the function of this array, the callback function is never invoked because the array has no actual elements.

Example ​

javascript
const list = new Array(5).map((_) => createElement());
