CLI Run JS - JavaScript

Introduction

CLI Run JS is a command-line interface tool that enables you to run JavaScript code snippets directly from your terminal, without having to open any external text editors or web-based coding platforms. It's fast, lightweight, and can be used for a variety of tasks, from simple calculations to more complex programming exercises.

Installation

CLI Run JS can be installed using the Node Package Manager (npm). To install, simply run the following command in your terminal:

npm install -g cli-run-js

Usage

To use CLI Run JS, open your terminal and type the following command:

cli run js

This will start the CLI Run JS environment, allowing you to enter JavaScript code snippets and execute them on the fly. You can execute any valid JavaScript code, including variables, functions, loops, and conditional statements.

For example, you can perform simple calculations, like adding two numbers:

let x = 5;
let y = 10;
let result = x + y;
console.log(result);

This will output 15 in your terminal.

You can also create more complex functions, like a Fibonacci sequence generator:

function fibonacci(num) {
  let a = 1, b = 0, temp;

  while (num >= 0) {
    temp = a;
    a = a + b;
    b = temp;
    num--;
  }

  return b;
}

console.log(fibonacci(7));

This will output 13 in your terminal, as it generates the 7th number in the Fibonacci sequence.

Conclusion

CLI Run JS is a powerful tool for any programmer looking to quickly test and experiment with JavaScript code snippets. Its simplicity and ease of use make it an essential tool for any development workflow. Give it a try today and see how it can improve your coding!
