Can you explain what the global execution context is in JavaScript?
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 the window object, while in Node.js, it's global.
How does the global execution context affect variable scope?
It defines the scope for variables declared outside of any function, making them accessible throughout the script.
Can there be multiple global execution contexts?
No, there is only one global execution context per JavaScript environment, but each function call creates a new execution context.
