What does "TL;DR" mean in programming?
TL;DR is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
Too Long; Didn't Read. A summary placed at the top (or bottom) of a long message, document, or post so readers can get the key point without reading everything. Writing a good TL;DR is a communication skill.
