Cascading refers to the process of styles being applied from parent elements to their child elements in CSS.

Recursion is a programming technique where a function calls itself to solve a problem.
Recursion involves breaking down a problem into smaller subproblems and solving them recursively.
A base case is needed to stop the recursive calls and prevent infinite loops.
Example: Factorial calculation using recursion - function factorial(n) { return n === 0 ? 1 : n * factorial(n - 1); }

Closures are functions that have access to their own scope, as well as the scope in which they were defined.
Closures are created when a function is defined within another function and has access to the outer function's variables.
Closures can access variables from the outer function even after the outer function has finished executing.
Closures are commonly used in event handlers and callbacks to maintain state.
