I recently started learning javascript which is one of the most popular programming languages. I had been able to use some programming language but it seemed difficult a little to use javascript. There are several points that differ from other programming languages. This is because javascript runs on a browser. I had learned it, and now I could write a simple program. In order to develop a more complex program, I wanted to use a debugger. By using a debugger, I can trace the flow of the program, and which increase productivity much. I studied how to use a javascript debugger. It was not easy since I was not familiar with javascript tools and environment. Finally, I could use a javascript debugger and could trace the flow of the program.
