·2 mins

In this post, I will try to document the different ways to run the javascript code.

As a beginner, you always need a simple way to run the code and test it.

Browser Console #

The best way to test a piece of code is Browser console.

Open any browser except Internet Explorer as it doesn’t support many modern javascript feature.

Press ctrl+shift+I or right click and select Inspect.

In the console tab you can write the javascript code and run.


Run Offline using Nodejs #

Install nodejs in your machine.

Write the javascript code in the .js file and run using node command.

Demo #

Create a file hello.js and paste the below code.

console.log("hello world!");

Open terminal or cmd in the location of hello.js.

Run the code using node.

node hello.js
