Deque is a double-ended queue data structure that allows efficient insertion and deletion at both ends. It's like a line at a trendy tech conference registration booth, where you can cut in line at either end, but everyone in the middle is stuck there, just like your legacy codebase.

How to use it in a sentence

• "I was going to use a deque for my task scheduler, but then I realized I could just use a bunch of if-else statements and hope for the best, like everyone else does around here."

• "Yeah, we used a deque to optimize our message passing system, but then the product manager decided to pivot to a blockchain-based solution because they read about it on Hacker News."

• Double-ended queue (deque) in Python: If you're into Python (and who isn't these days?), this article explains how to use the deque class from the collections module, complete with code examples you can copy-paste and call your own.

• C++ std::deque: For those of you still stuck in the world of C++, this reference guide covers the std::deque container, which is like a deque but with more angle brackets and less joy.
