👉 Underjacket is a term used in the field of computer science, particularly in the context of software development and testing. It refers to a type of software that does not follow the conventional "correct" or "best" implementation of a programming language or standard. Instead, it relies on its own internal mechanisms and algorithms to achieve its functionality. Underjackets are often used in situations where performance and reliability are crucial, as they can be designed to work under high load conditions without compromising on their performance
