oxc/uninvoked-array-callback Correctness
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());How to use
To enable this rule in the CLI or using the config file, you can use:
bash
oxlint --deny oxc/uninvoked-array-callbackjson
{
"rules": {
"oxc/uninvoked-array-callback": "error"
}
}
