JavaScript, like most programming languages, manages different types of memory to handle variables, functions, and data in your program. Understanding the different types of memory and how they work is essential for writing efficient, scalable, and performant JavaScript code. In this detailed article, we will explore the different types of memory in JavaScript, their use cases, and how they differ from each other.
