Overall, Node.Js significantly improves web server performance by boosting the speed and continuing the next request. But for all that to happen, developers need to implement its advantages for best results properly. There are some things you should know about Node.Js and understand it’s pitfalls first.
That’s why in this article, we’ve listed the most common mistakes that you should avoid to never go wrong with Node.Js development.
A common issue we previously referred to as the “callback hell” is calling a callback more than once. Developers often save a file and reload the Node.Js app to see if it crashes fast. It results in multiple callback executions, as they didn’t return after the first time.
Being careful means avoiding this mistake. For that reason, some developers have a habit of adding a return keyword before a callback invocation. In many functions, this has no significance, so it only makes it easier to avoid such issues.
The floating-point numbers can hold integer representations up to a specific value. Exceeding it would instantly mess things up. Dealing with large numbers rarely happens, as we mentioned. Still, if you want to, you can find integer libraries, which implement the essential math operations on large precision numbers.
There are some great libraries built, especially for debugging, so there’s no reason to use console.log for this task. Such packages provide convenient enough ways to disable or enable debug lines when you start the app. Using debug is simple and more efficient.
