Array.isArray method
The Array.isArray method checks
if the given object is an array. If so,
then true is returned, otherwise
- false.
Syntax
Array.isArray(value to check);
Example
Let's check if our object is an array:
let res = Array.isArray([1, 2, 3, 4, 5]);
console.log(res);
The code execution result:
true
Example
Let's see if the next object is an array:
let res = Array.isArray({'a': 1, 'b': 2, 'c': 3});
console.log(res);
The code execution result:
false
