What Is JavaScript's Execution Context? - JavaScript Toolkit

What Is JavaScript's Execution Context? Have you ever wondered how JavaScript manages the execution of your code behind the scenes? In this detailed video, we'll explain everything you need to know about JavaScript's execution environment. We'll start by defining what an execution context is and how it functions within the JavaScript engine. You'll learn about the two main types of execution contexts: global and function, and how they are created and managed during code execution. We'll discuss the concept of the call stack and how JavaScript handles function calls one at a time, helping you understand the flow of your program. Additionally, you'll discover the two phases of execution—creation and execution—and how hoisting works during the setup phase. We'll also explore how variables and functions are stored and accessed through environment records and scope chains, including the concept of closures. Whether you're a beginner or looking to deepen your understanding of JavaScript, grasping how execution contexts work is essential for writing predictable and efficient code.
