Recursion

 Roadmap of frontend development: HTML and CSS: Start with HTML and CSS as the foundation of your knowledge. These two primary languages lay the groundwork for developing all web pages and web applications. JavaScript: Learn the fundamentals of JavaScript, which is the programming language used to build interactive and dynamic elements on the website. Frameworks and Libraries: Learn one or more popular front-end frameworks and libraries such as React, Angular, Vue, jQuery, or Bootstrap. These tools will help you build more complex and scalable front-end applications with less code. Package Managers: Install and configure package managers such as npm or yarn to manage project dependencies, and learn how to use build tools such as Webpack or Gulp to automate the build and deployment process. Version Control: Version control systems like Git are essential tools for managing code and collaborating with other developers. Learn how to use Git and online repositories such as GitHub, GitLa...

  Recursion: It is a powerful and elegant programmatic technique that allows a function to call itself, either directly or indirectly, to solve a problem. It is a fundamental concept in computer science and is used in many programming languages, including Python, Java, C++, and many others. At its core, recursion involves breaking down a problem into smaller sub-problems and solving them recursively. When a recursive function calls itself, it does so with a smaller input, and the function will eventually solve the problem by reducing the input to a base case. The base case is the simplest possible problem that can be solved for the given input. The base case tells the recursion when to end, and without it, the function will continue to call itself indefinitely, leading to a stack overflow error. One of the most common examples of recursion is the calculation of factorials. A factorial is defined as the product of all positive integers up to a given number. For example, the factoria...
