Benefits of the Debugger Tool

The various benefits of the debugger are:

• Understand and debug code: You can use the debugger to understand the code line by line and, if required, find bugs in the code. The debugger is simple to use and allows you to find bugs very easily.
• Inspect expressions and variables: You can check the values of specific variables or expressions by adding them to the underwatch expressions. It helps a lot in checking the changes in the values of the variables as the execution proceeds.
• Format option and color code: The code can be formatted to look clean and readable. The code is also viewable in color, which gives you an idea of various code constructs.

Firefox provides a debugger in the DevTools to examine the JS code of the web page to inspect or find various bugs. You can add breakpoints to control the flow of execution and inspect various variables. All developers must know how to debug their code and since the debugger is easy to use it won’t be a big task to learn.
