Welcome to my Node.js tutorial series! Through this video, explained about REPL In Node.js, REPL stands for Read-Eval-Print Loop. It's an interactive programming environment that allows you to enter JavaScript code, which is then interpreted and executed by Node.js. The REPL provides a way to experiment with Node.js code, test small snippets, and explore the behavior of JavaScript functions and objects in real-time. Here's a breakdown of the components of the REPL: Read: The REPL reads user input, typically JavaScript code, from the terminal. Eval: The input received is evaluated and executed as JavaScript code. Print: The result of the evaluated code is printed to the console. Loop: The process continues in a loop, waiting for further input from the user. To start a Node.js REPL session, you can simply type node in your terminal and press Enter. You'll see a prompt where you can start typing JavaScript code. Pressing Enter after each line of code will cause it to be evaluated and executed, with the result printed to the console if applicable. To exit the REPL, you can type .exit or press Ctrl + C twice.
