    //we need to wait for one of them to finish before adding another one
    while (tmpPromises.size >= MAX_APEX_CALLS){

      //Not the first in the array, but in any position

      //The finally clause of the promise runs
      //This removes the finsihed promise from the temp Array to allow the next Apex call
    }

let apexPromiseResults = mapParallel([Array Of Params To send To Apex...],

              });

//now you can loop over the results from apexPromiseResults
