Returns the index of the function in an array of functions which executed the fastest.
Use `Array.map()` to generate an array where each value is the total time taken to execute the function
after `iterations` times. Use the difference in `performance.now()` values before and after to get the total time
in milliseconds to a high degree of accuracy.
Use `Math.min()` to find the minimum execution time, and return the index of that shortest time which
corresponds to the index of the most performant function. Omit the second argument, `iterations`, to use a default of 10,000 iterations. The more iterations, the more reliable the result but the longer it will take.
