One of the key features of Chrome’s Developer Tools is the ability to set breakpoints in your code. This allows you to pause the execution of your code at a specific point and inspect the values of variables and other data. This can be incredibly helpful for identifying bugs and other issues in your code.
In addition to debugging tools, Chrome’s Developer Tools also include a range of performance analysis tools. These can help you identify areas of your code that may be causing performance issues, such as slow-loading scripts or memory leaks.
