Course Introduction:In this tutorial, we will learn about the method of checking whether a given data type is primitive or not. Data types in JavaScript 1. Primitive data types 2. Non-primitive data types Primitive data types - string, number, undefined, boolean, null, symbol, bigint. Non-Primitive Data Types - Objects A primitive data type/value is not an object, it is represented as the underlying language implementation. All primitive values are immutable which means you cannot change their type but can reassign new values to variables. To check if the value is a primitive, we check if the given value is an object; if the value we provide is an object, it means that it is not a primitive data type using certain methods. Method 1: Use Obje
