In JavaScript, the "execution context" is a fundamental concept that helps to manage the execution of code. It can be thought of as an environment in which the code is evaluated and executed. Whenever a JavaScript program runs, it creates one or more execution contexts, each representing a particular scope, set of variables, and the rules for how the code is executed.
To understand in easy language, imagine your JavaScript code is like a play, and the execution context is like the stage where the play is performed.
The execution context is where your code comes to life. It keeps track of all the characters (variables) and their lines (values) as they interact with each other. Each time a function is called or code is executed, a new performance (execution context) is set up on the stage.
This stage knows about other stages too, so if one function needs something from another function, they can talk to each other.
When a function finishes its performance, the stage is cleared, and the next one gets ready for its turn.
This way, each part of your code gets its own stage (execution context), and they don't interfere with each other's performance. It's like a well-organized theater production, making sure everything runs smoothly and without any chaos!
