Even for professionals, coding is not easy. This is probably why developers spend a lot of time looking for bugs in their code. Sometimes a bug is obvious, causing the whole program to crash at once. Other times a bug is very subtle, producing good-looking output that always contains flaws.

As counterintuitive as it may sound, obvious bugs are better because they are easier to find. A sneaky bug can lurk in everyday software for years.

Think of it this way: If you were in a building that was slowly filling up with poison gas, you would want the gas to be odorless, tasteless and colorless, or bright purple and smelling like powder. cannon?

Debugging is a crucial step in the development process , there are many tools available to do this. Today we are going to talk about debugging JavaScript in Chrome. Javascript is by far one of the most popular languages ‚Äã‚Äãoverall and arguably the most popular language for web development. Likewise, Chrome is one of the most used web browsers.

As someone who will soon be a in-demand web developer , it’s a good idea to familiarize yourself with JavaScript debugging with Chrome. I encourage you to follow this elegant example webpage > created specifically to practice debugging.

Using the Source panel

The "Elements" tab allows you to browse the HTML and JavaScript that make up the web page. The "Console" tab gives you space to tinker with JavaScript. Open the console for the example page linked in the section previous and type console.log (’hello’). This JavaScript command should run in your browser.

The ’Sources’ tab shows you the actual content of the page’s source files and gives you a way to set breakpoints and inspect the call stack.

Breakpoints and debuggers ;

Along with printing instructions, breakpoints are one of the basic techniques used by developers for debugging.

Defining a breakpoint shutdown in the Chrome console is simple - just click on the number √©ro I was from the line that interests you A breakpoint is a place where the code automatically stops in its execution. This allows you to inspect everything that has happened so far, including things like the current value of each variable and any transformations that have taken place.

Breakpoints are a great way to check the progress of your code to see if something has gone wrong.

We can achieve the same effect manually by placing the debugger; in our code where we want to start the debugging process.

By setting multiple breakpoints, we can get a close-up view of everything our code is doing, making it much easier to spot errors.

While this is certainly not all you need to master the art of debugging, it is a nice plus. The most correct code correction is to think very patiently and very clearly about what you wanted to do with your code and compare it to what you actually said in your. . ;

With the above information, you are on your way to running JavaScript Debugging with Chrome.
