This object can measure the time a function takes to execute.

It takes a given function and calls it consecutively a given number of times.

The class returns the output of the function and the time that it took to execute the function in microseconds and milliseconds.

Winner		 Sometimes it is necessary to optimize the performance of a given piece of JavaScript code.

This object allows to measure the time a function takes to execute many times, so you can evaluate more accurately if any optimizations have benefited the overall performance of the code of that function.
