Javascript Check if an Object Is an Array

This content originally appeared on CodeSource.io and was authored by Deven

In JavaScript To check if an Object Is an Array we use the static Array.isArray() method.

const fruitNames = ['Apple', 'Mango', 'Banana', 'Grapes', 'pineapple'];
if (Array.isArray(fruitNames)) {

// Our code ends here because it is a valid array
}

isArray() specifically checks for instances of the Array object. If we call it on a different type of collection like Map or Set, it returns false.
