The clean-up step may seem strange, but it’s a memory-usage optimization. When a language runtime executes a series of function calls it does not need to keep already-exited stack frames around. Branching function calls only form a tree in the time dimension; at any given snapshot in time there exists only a single stack of function calls in memory, tracing the current path through the tree. If we did not set our child frames to null we would end up building the whole tree up in memory and retaining it until the recursive processing is complete. Removing references to them allows the runtime to reclaim their memory at its leisure. If you’ve ever wished that you could deal with manual memory management in JavaScript, now’s your chance!

I've been doing OSS since 2009ish. My first "success story" was libGDX, a cross-platform game development framework. Back in 2011, it was all the rage and the most used game development framework on Android. Some prominent libGDX users included Niantic (Ingress was built with libGDX, Pokemon Go was not) and the peeps behind Slay the Spire. It also powers Spine, a commercial game development tool I've been involved in for almost 10 years now.
