Understanding the Difference Between .js and .txt Files in JavaScript Development

In  JavaScript programming, two typical file extensions are frequently used: .js and .txt files. While they may look identical at first sight, there are significant differences between them, and knowing these differences is critical for every developer. In this article, we will look at the distinctions between.js and.txt files and understand why we choose to run JavaScript code in.js files.

1. File Extension:
The most noticeable distinction between.js and.txt files is in their file extensions. The ".js" extension is used for.js files, whereas the ".txt" extension is used for.txt files. This naming standard aids developers and systems in determining the file's kind and purpose.

2. Purpose:
Both.js and.txt files can be used as source code. Their principal goals, however, are vastly different. .js files are designed particularly for JavaScript code. They include JavaScript code snippets or whole scripts that may be run by web browsers or server-side environments. .txt files, on the other hand, are commonly used for storing unformatted textual data such as notes, manuals, or configuration information.

3. Execution:
The primary reason for using .js files to run JavaScript code is that they are intended to be interpreted and performed by JavaScript engines. Web browsers and Node.js, for example, may comprehend and run the code contained within .js files directly. In contrast, .txt files lack this intrinsic execution capability. They are not recognized as JavaScript code, and running them as such will result in problems.

Conclusion:
In summary, the main difference between .js and .txt files is their intended purpose and execution capabilities. .js files are specifically meant for JavaScript code and can be executed by compatible environments, while .txt files are generic text files without built-in execution capabilities. Therefore, when you want to create JavaScript applications or scripts, it's essential to use .js files to ensure your code can be properly executed and achieve its intended functionality. Understanding these distinctions will help you make the right choices when organizing and managing your JavaScript projects.
