Understanding Log4Shell: An Ultimate Guide to Protecting your System
Coding is a big part of building an application. But, most of the time, you don’t write the entire code. Yes, you don't! Some people, usually big companies, provide pre-written codes for certain standard functions - like loggers, APIs, etc. This is because these functions work the same way in most applications; they require only simple fine-tuning to be adapted for your program as well. In such a case, writing it all from scratch would be a waste. And that is why developers use libraries.
