What is a .JS file?
A .JS file is a type of plain text file specifically used for writing JavaScript code. JavaScript is a programming language that helps make webpages interactive. This means that a .JS file can contain code that does things like opening and closing windows on a website, checking if the information in a form is correct, changing images when you hover over them, or creating dropdown menus.
To use JavaScript code on a website, developers often link a .JS file to the HTML of the webpage. This is usually done by placing a reference to the .JS file in either the `
` or `` section of the HTML code. For example, you might see a line like this in the HTML: ```html ``` This line tells the browser to load and use the JavaScript code from the "example.js" file while loading the webpage.Because .JS files are plain text, you can open them with a variety of programs. Developers typically use specialized code editors because these programs provide helpful features like syntax highlighting and code completion. Some of the popular programs for opening and editing .JS files include: - Microsoft Visual Studio Code - Adobe Dreamweaver 2021 - JetBrains IntelliJ IDEA - Brackets - Any general text editor like Notepad or TextEdit - Web browsers can also open .JS files, mainly for the purpose of running the JavaScript code within them.
For those using mobile devices, there are apps like File Viewer for Android that can open .JS files.
In addition to these tools, there are also discontinued programs like Github Atom, which was once popular for editing such files.
Overall, .JS files are essential for web developers looking to add dynamic content and interactive features to webpages, and they are supported by a wide range of software across different platforms.
