This article mainly introduces the application scenarios of debugger in javascript, which have certain reference value. Interested friends can refer to it. I hope you will have a lot of gains after reading this article. Let Xiaobian take you to understand it together.

1. Logically complex algorithms.

If you brush leetcode, you will have a deep understanding. One of the test cases in the algorithm is wrong, and sometimes it is difficult to find the problematic method visually.

2, copy the steps are very cumbersome bug.

It took 10 minutes to reproduce, but only one line of code was traced, and a second log was needed to continue looking for the problem. View log-> Add log-> View log... This process was repeated a few times, and the remaining bricks would not be finished today.

3, the process of running lengthy code.

4, no comments, named arbitrary code.

5. Code server side.

Those who have experience with nodejs server development believe that they have experienced postman->ide repeated lateral jumps. If you rely solely on logs, it is difficult for the console to see the whole picture of a large and complex object. If an interface also involves database additions and deletions and third-party dependencies, it is painful to recover the consequences of the last request.

Thank you for reading this article carefully. I hope that Xiaobian will share the article "What are the application scenarios of debugger in javascript?" This article is helpful to everyone. At the same time, I hope that everyone will support you a lot and pay attention to the industry information channel. More relevant knowledge is waiting for you to learn!
