What is the global execution context in JavaScript?

Can you explain what the global execution context is in JavaScript?

Sure! The global execution context is the default context in which JavaScript code runs. It creates a global object and sets up the environment for the code.

What does the global object contain?

The global object contains all global variables and functions. In browsers, it's usually the window object.

How does the global execution context differ from function execution context?

The global execution context is created once when the script runs, while a function execution context is created each time a function is invoked.

Can you give an example of how the global execution context is used?

Certainly! For instance, if you declare a variable outside of any function, it becomes a property of the global object, accessible anywhere in your code.
