A breakpoint is an intentional stop or pause placed in an object. It is a mark that you can set on a statement. When the program flow reaches the statement, the debugger intervenes and suspends execution until you instruct it to continue. During the interruption, you can inspect the environment, or start line-by-line code execution.
There are several methods for placing and removing breakpoints. This section will show you all the different ways, so that you can choose the one that best suits your debugging needs.
