Have you encountered a problem with a JS file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a JS file here. In the further part of this page we have added a list of programs that should open your JS file. It is enough you choose a proper application for your operating system, download and install it.

Description

Files with the suffix JS contain JavaScript or JScript source code. JScript is the JavaScript variant of Microsoft.

JavaScript, not to be confused with JAVA is a programming language specially adapted to the needs of web programmers. The scripts written in it are processed by the browser and allow a website to be changed dynamically. This does not happen on the web server, but in the browser of the user. Therefore, there is some security risk with JS files.

However, JavaScript is very common and many modern offers, often referred to as WEB 2.0, do not work without JavaScript processing.

The JS file contains the source code, but it does not have to be pure JavaScript. It can also be based on one of the numerous JavaScript libraries, such as Mootools or jQuery. Even AJAX applications like Google Maps use JavaScript.

To edit a JavaScript file, a simple text editor is sufficient, but a special editor is preferable. This recognizes the language elements, presents them color coded and structured.

Any browser can execute JavaScript, but the results are quite different.

How to open a JS file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the JS file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a JS file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support JS files. At this point we are looking for disk space where the application was installed in and we can link it with a JS file. Since then, our operating system will use the selected program to support all JS files.

Other issues

Despite the described problem with JS there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the JS file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the JS file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
