add times function

[shevv920]

times receives as arguments the function to execute n times and a number of iterations, and returns an array of the results. Very useful when creating dynamic test data.

const randomBool = () => Math.random() > 0.5;

const result = times(randomBool, 5);
// result: [true, false, false, true, false]
