@putout/plugin-apply-is-array

The Array.isArray() method determines whether the passed value is an Array. When checking for Array instance, Array.isArray() is preferred over instanceof because it works through iframes.

(c) MDN

🐊Putout plugin adds ability to apply Array.isArray(). Fits good with @putout/plugin-declare. Merged to @putout/plugin-types.

Install

npm i @putout/plugin-apply-is-array

Rule

{
    "rules": {
        "apply-is-array": "on"
    }
}

❌ Example of incorrect code

x instanceof Array;

✅ Example of correct code

const {isArray} = Array;
isArray(x);

In case of using inline option:

{
    "rules": {
        "apply-is-array": ["on", {
            "inline": true
        }]
    }
}

Array.isArray will be inlined:

Array.isArray(x);
