REPL (Read-Eval-Print Loop)

A REPL (Read-Eval-Print Loop) is a system used by programmers to interact with a programming language in real-time. It works by reading your input (Read), understanding and executing your code (Eval), and then showing you the result (Print). After that, it waits for your next command. This cycle continues, allowing you to test ideas, debug, or learn the language efficiently. REPLs provide an immediate, interactive environment, making programming more dynamic and accessible for experimentation and development.
