How to Run Recursion 100,000 Times Without Stack Overflow (Tail Call Optimization)
Preventing Stack Overflow. Just pass the baton and go home. Why compilers love TCO.

Fast by name. Partitioning around a Pivot. Why is it the standard library choice despite O(N²) worst case?

Tired of naming classes? Writing CSS directly inside HTML sounds ugly, but it became the world standard. Why?

Establishing TCP connection is expensive. Reuse it for multiple requests.

Why does my server crash? OS's desperate struggle to manage limited memory. War against Fragmentation.

TCO teaches us that underneath the syntax sugar, recursion and loops are the same thing (Jumps). Knowing TCO makes you a better engineer, not so you can use it everywhere, but so you understand the cost of your abstractions.
