Control Stack Size

1. Dilemma

While I was testing my basketball website, specifcally the play by play stats, the entire website crashed when loading one of the pages. Prior to this crash, the website had never gone down when loading a page. So this error came as a surprise to me.

As show in the image there is an error, "Control stack exhausted (no more space for function call frames), is "probably due to heavily nested or infintely recursive function calls."

2. Understanding the Dilemma

The dilemma ended up being due to the list of arguments exceeding the call-argument-list. This was a result of using the apply function in a few of my other functions. With apply every time it it runs through an argument, it "stacks the value" because it is a non-optimized recusion function. If it "stacks" enough times where it reaches a limit it invokes the "Control stack exhausted."

3. Solution

Instead I used the function reduce where it repeats the function with two functions. This essentially "optimizes" as it goes through the arguments so there wont be the "stacks" that would have happened had apply been used.
