How to run javascript on local server

Local server is a software used to run web applications on the local computer. The server serves as the host of the web application, receiving user requests and returning corresponding web pages. A local server running JavaScript can help web developers test and debug their code to ensure they work properly across different browsers and devices. This article will explain how to run JavaScript on a local server on different operating systems.

1. Running a local server under Windows system

The easiest way to run a local server under Windows system is to use XAMPP software. XAMPP is a cross-platform web server solution that can run Apache, MySQL and PHP simultaneously. To use XAMPP on Windows systems, you first need to download and install it, and then run the Apache server. After starting the Apache server, you can place the local folder into Apache's "htdocs" folder and then enter "localhost/filename.html" in the browser to access the file.

2. Running a local server on MacOS system

Summary

Whether you are running Windows, MacOS, or Linux, you can use the appropriate software to run a local server and test your JavaScript code. A local server can be a very useful tool when you need to test your web application on different browsers and devices. Starting a local server allows you to check the final display of your website more quickly, and also allows you to test and debug code more conveniently in front-end development.
