WebMar 18, 2024 · 1. No it doesn't. Recursion doesn't run "in the same function", every time you recurse you start a new function call, like a giant chain where every part of the chain is the same function but called with different input. When a return happens, you leave the current function call, and the code picks up where you left the previous function call.
