1. Avoid Image Optimization

Image size optimization is essential for reducing your web application’s bandwidth usage. Assume your landing page has ten images, and each is 5 MB or higher. The user will not wait for the page to load. Use SVGs for logos, icons, and other images rather than using JPG or PNG. Keep avoiding image optimization because many free online tools can help you optimize JPG and PNG images.

2. Cross-Browser Incompatibility

The majority of the time, development processes have a tight deadline. As a result, when debugging an application, developers typically use only one browser. That’s great if you have time later to test it on different devices and fix any bugs. So, if you don’t have much time, it’s a good idea to test the app in other browsers while developing. It’s not something you can avoid. At least three major browsers, including Chrome, Firefox, and Microsoft Edge, must be used to test your application. Many UI issues arise in Firefox, which does not exist in Chrome.

Try and make your web programs as cross-browser flexible as possible. Avoid utilizing browser-specific code, and remember that cross-browser compatibility is usually tricky.

3. Ignoring Code Formatting and Commenting

There’s a possibility that a newbie developer created a set of JavaScript code lines without formatting, unnecessary blank spaces, useless newlines, and poor naming standards. No skilled developer would do such things because they know how difficult it is to look at wrongly formatted code. Learn the naming rules for the languages you use, write functions and variables correctly, and use your IDE’s automatic code format tool.

Writing relevant comments to the code is another helpful practice used by skilled developers but ignored by beginners. Adding comments would be to document your code so other developers can know it later. You use the Comment to identify variables, functions, class names, and the high-level functionality of your code.

4. Trust Open Source Blindly

The majority of developers have total trust in open source. What they don’t realize is that the companies behind such software are only interested in profit. It should continually evaluate an open-source solution.

5. Write CSS and JavaScript in HTML Files

As it is among the most common errors in the books, developers continue to make it. It is often the most convenient option, and the most suitable choice isn’t simply the right one. It’s a poor technique that will make your code unclear and hard to test and debug. Security problems, among many other issues, are all possible. To keep the proper project structure, always write JavaScript and CSS in separate files.
