Summary of JavaScript debugging tools_javascript skills

Now JavaScript has actually become a popular web language, even if it is not perfect. Many programmers don't like to write code in JavaScript because all kinds of inexplicable bugs always appear after writing, and it's easy to make mistakes in the process of developing large applications. And given the current state of such tools today, it’s not that convenient to do JavaScript debugging in the browser.

The following desktop and WEB-based JavaScript debugging tools allow you to debug JavaScript code more efficiently, so you can:

Handling dynamic types more efficiently makes applications more compliant with coding standards

Firebug

Firebug has been around for many years and provides an app extension for developers who primarily create apps on Firefox.

is a dedicated application for HTML, CSS and JavaScript testing. It is more powerful than the developer tools that come with the default browser and allows setting breakpoints to facilitate testing results at various stages

If you are developing programs on other browsers, such as Google's Chrome browser, you can try the streamlined version of Firebug. The functions are the same, but the interface is slightly different.

Summary:

We may find JavaScript cumbersome, but that’s because it will evolve gradually, rather than being some grand design from the beginning. The tools and applications above can benefit your development and testing. And there is always a browser that suits you, helping you develop apps more efficiently and without bugs.
