Recursion in JavaScript

Recursion in JavaScript refers to a function calling itself repeatedly until it meets a termination condition called the Base Case. This process allows solving problems by breaking them into smaller instances of the same problem. For example, recursion can be visualized as running laps on a track that get progressively smaller. To avoid infinite calls, a base case ensures that the recursion terminates. Common use cases of recursion include generating Fibonacci Series, checking for Palindromes, and finding the Longest Common Subsequence.

In Example 1, a decrement counter demonstrates recursion by decrementing a number by one and printing the sequence until it reaches 0. Example 2 illustrates recursion for determining whether a number is even or odd by repeatedly subtracting 2 and checking if the result is 0 or 1. These examples showcase how recursion processes a task step-by-step while meeting the base case for termination.
