Generates a list of random numbers between -1.5 and +1.5 then loops through the list with each function. Functions that uses branches should have more variance in speed since they can potentially exit early. Functions that use arithmetic should have little to no variance but do more computation.

Test the performance of Array.find vs. Map.get, with various array sizes, and with/without conversion from array to map

Both structuredClone(myObject) and JSON.parse(JSON.stringify(myObject)) can be used to create deep copies of JavaScript objects, but which is faster for a decent sized object?

which is faster for converting raw html into textContent
