What are closure and scope in JavaScript?

Can you explain what closure and scope are in JavaScript?

Sure! In JavaScript, scope refers to the visibility of variables, while closure is a function that retains access to its lexical scope.

How do closures work in practice?

Closures allow a function to access variables from an outer function even after the outer function has executed.

Can you give me an example of a closure?

Absolutely! Here's a simple example: function outer() { let count = 0; return function inner() { count++; return count; }; } The inner function has access to the count variable.

What about scope? How does it differ from closure?

Scope defines where variables can be accessed, while closure is a feature that allows a function to remember its outer scope.
