Opening JS files

Did your computer fail to open a JS file? We explain what JS files are and recommend software that we know can open or convert your JS files.

What is a JS file?

Files containing the .js extension are most commonly associated with JavaScript files. These JS files contain JavaScript code that is used to execute instructions in a Web page that uses client-side scripting. The functions may include the validation of form fields, rollover images, drop-down menu creation and other functions.

The .js file extension is also used for JACOsub script files, JetScript output files, Netscape settings files and ECMAScript language files.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
