In this article, I will describe the ways to handle errors accurately and without painful disturbance of a complex code. Most of the programmers don’t use error handling the way it should be, and also we ignore the error logs that need to be maintained. Why do we need these things? I will explain this as a beginner in this technique. There might be more good articles on it but the purpose of my article is to let beginners understand why, how, and when to use error handling and logs, with different scenarios.-In this article, I will describe the ways to handle errors accura tely and without disturbance of a painful compl ex code.
