What is the difference between execution context and scope?

Can you explain the difference between execution context and scope in JavaScript?

Sure! Execution context is the environment in which JavaScript code is evaluated and executed, while scope refers to the visibility of variables in different parts of your code.

How does the execution context affect variable scope?

The execution context determines which variables are accessible at any given time, based on where the code is executed. Each function creates a new execution context, which can have its own scope.

Can you give an example of execution context in action?

Absolutely! When a function is called, a new execution context is created. For instance, if you have a function that defines a variable, that variable is only accessible within that function's execution context.

What happens to the scope when a function is nested inside another function?

In nested functions, the inner function has access to the outer function's scope due to lexical scoping. This means it can access variables defined in the outer function.
