const getType = v =>
   v === undefined ? 'undefined' : v === null ? 'null' : v.constructor.name.toLowerCase();
-
getType(new Set([1, 2, 3])); // 'Set'
+
getType(new Set([1, 2, 3])); // 'set'

isArray

Checks if the given argument is an array.

Use Array.isArray() to check if a value is classified as an array.

const isArray = val => Array.isArray(val);
 
isArray([1]); // true

isArrayLike

Checks if the provided argument is array-like (i.e. is iterable).

Use the spread operator (...) to check if the provided argument is iterable inside a try... catch block and the comma operator (,) to return the appropriate value.

const isArrayLike = val => {
