Preventing Stack Overflow. Just pass the baton and go home. Why compilers love TCO.
Why does my server crash? OS's desperate struggle to manage limited memory. War against Fragmentation.
Two ways to escape a maze. Spread out wide (BFS) or dig deep (DFS)? Who finds the shortest path?
Fast by name. Partitioning around a Pivot. Why is it the standard library choice despite O(N²) worst case?
Establishing TCP connection is expensive. Reuse it for multiple requests.
TCO is beautiful and elegant computer science knowledge.
But in practical work, especially web development, "Just use a for loop" is the correct answer.
"Elegant code isn't code that machines find easy to execute (though TCO is nice), it's code that your colleagues find easy to understand."
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.
