Primitive vs Reference - What's the difference - JavaScript Bangla ( বাংলা ) Tutorial

In JavaScript, a variable may store two types of values: primitive and reference. JavaScript provides six primitive types as undefined, null, boolean, number, string and symbol and one reference type called object. In this tutorial, you will learn the differences between primitive and reference values. While doing so, you will also learn some fundamental concepts such as memory allocation in stack and heap, master object, wrapper primitive types and function parameter pass by reference. You will also understand how to copy sensitive reference values immutably which will help you working with state management in popular JavaScript libraries like React, Vue etc.
