Learn how to open a .JS file effortlessly and explore the world of JavaScript programming. Follow our step-by-step guide for beginners. If your objective is to work programming the .JS lines of code in the Windows of your PC, first you must know what they are and how they work. That is why in this tutorial we will briefly explain how to open a .JS file and work with them.
What is a .JS file?
A file extension is the series of 3 or 4 characters found at the end of the name of a document. The extension files tell the programmer what kind of document it is, and the information it has in relation to Windows.
Windows windows are often associated with a list of .JS codes, which are collated with each file extension . For that reason, when you double-click on the document you chose, it will automatically open on your computer.
But of course, when you delete the document from your computer, all the information related to the .JS file extension will also be deleted. For that reason, even if you get a reference to the document, when you try to open it, the PC will tell you that there is a failure.
How to open a .JS file?
The process to open the .JS file is simple, but the programmer must verify that the computer has an application compatible with the program . For that reason, in this tutorial we will briefly explain what you need to do to open this document so that you can use it correctly.
To open a .JS file extension, you can do it like any other document that you want to select on your PC, you must double-click it . If the combination of the files are properly defined, the application that opens the .JS will allow it to open properly.
You will have to verify that your computer has the appropriate application to open the .JS application and if you do not have it, you will have to buy it. Since, if you do not have the ideal application for this file, you will not be able to open the document, no matter how much you try to do it through Windows.
Applications that will allow you to open .JS
In order to open a .JS file, we must have one of these applications, which PCs normally have built-in .
- Microsoft Notepad, which can be downloaded from the Microsoft Store .
- Microsoft Internet Explorer.
- Apple Safari.
- Google Chrome.
- Mozilla Firefox.
To open a .JS (JavaScript) file on your Windows PC and view its content in a tabular format, you’ll need to follow these steps:
- Text Editor:
- You can use a text editor to open and view the contents of the JavaScript file. Notepad is a basic text editor that comes with Windows, but for a more feature-rich experience, you can use editors like Visual Studio Code, Atom, or Sublime Text.
- Visual Studio Code (VSCode):
- If you don’t have Visual Studio Code installed, you can download and install it from the official website: Visual Studio Code.
- Right-click on the .JS file.
- Choose “Open with” and select “Visual Studio Code” or open Visual Studio Code and use the File > Open File option.
- Viewing as a Table:
- JavaScript files typically contain code rather than tabular data. If your JavaScript file does contain structured data that you want to view as a table, you may need to parse and process the data using JavaScript code or another tool.
- You might consider writing a simple HTML file that includes a table and use JavaScript to populate the table with the data from your .JS file. This would involve understanding the structure of the data in your .JS file and writing JavaScript code to extract and display it in a table.
Here’s a basic example using HTML and JavaScript:
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Table Viewer</title>
</head>
<body>
<table border="1">
<thead>
<tr>
<th>Column 1</th>
<th>Column 2</th>
<!-- Add more columns as needed -->
</tr>
</thead>
<tbody id="tableBody">
<!-- Table rows will be added here using JavaScript -->
</tbody>
</table>
<script>
// Load your JavaScript file and process its data
fetch('yourfile.js')
.then(response => response.text())
.then(data => {
// Parse and process your data
// For example, if your data is an array of objects
const dataArray = JSON.parse(data);
// Iterate through the data and populate the table
const tableBody = document.getElementById('tableBody');
dataArray.forEach(item => {
const row = document.createElement('tr');
row.innerHTML = `<td>${item.property1}</td><td>${item.property2}</td>`;
// Add more cells as needed
tableBody.appendChild(row);
});
})
.catch(error => console.error('Error loading file:', error));
</script>
</body>
</html>
Replace 'yourfile.js' with the actual path to your .JS file and adjust the code according to the structure of your data. Keep in mind that JavaScript files are typically used for code rather than tabular data, so the format of your data will determine how you need to process and display it.
A very useful caveat regarding the .JS file
This is a very important point to take into account, so be very attentive to it and avoid taking undue attributions . In this way, you will make your .JS file extension work correctly and fulfill the function for which it was programmed.
What do we mean, good that some programmers tend to modify the extension of the .JS file, but this should not be done. Why? because, this will not cause the file type to be modified, since this will only be done by the indicated software. And this is, a special conversion software , which allows the .JS file to be modified by another type of file.
As you may have noticed, opening a .JS file is very simple, which allows you to carry out programming in your Windows. But it is also important to try not to modify the document unless you have a suitable software converter for it.
