JavaScript has actually become a popular web language today, even if it is not perfect. Many programmers don’t like to write code in JavaScript because they always have various inexplicable bugs after writing, and they are easy to make mistakes in the process of developing large applications. Moreover, given the current situation of such tools, it is not so convenient to debug JavaScript on the browser.
The following JavaScript debugging tools based on desktop and WEB can enable you to debug JavaScript code more efficiently, so that you can:
More efficient handling of dynamic typing makes applications more coding standards
Firebug
Firebug has been around for many years and it provides an app extension for developers who primarily create apps on Firefox.
It is a dedicated application that does HTML, CSS and JavaScript testing more powerful than the developer tools that come with the default browser. This 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 simplified version of Firebug, which has the same functions, but the interface is slightly different.

Other browsers are also improving to match Opera Dragonfly, but for now it is still one of the best testing tools for web developers.

Summarize:
Maybe we think JavaScript is cumbersome, but that's because it will evolve gradually, rather than being a grand design from the beginning. The above tools and applications can benefit your development and testing. And there is always a browser suitable for you to help you develop apps more efficiently and without bugs.
