So there seem to be no array functions like push(). pop() splice(), etc. so I am wondering how folks store data sets of unknown length at runtime - and retrieve that data in a for loop through some eq. of myArray.length - 1?
The only idea that comes to mind right now is to init an array with a length large enough to accommodate any possible data set and keep a separate index to the position of the last stored value.
Am I missing some built in methods?
