Use the Array.isArray() method to verify that the value is not an array - !Array.isArray(obj).Verify the value is not null - obj != null.Use the typeof operator to verify that the variable type is object - typeof obj = 'object'.To check if a value is an object, the above isObject() method does the following: This is because the arrays are internally treated as objects in JavaScript: const fruits = const user = We can not use the typeof operator as it returns object for both arrays and objects in JavaScript.
Today, you'll learn how to check if a variable is an object. In an earlier article, we looked at different ways to find out if an object is an array in JavaScript.
