Randomness in p5js is based on generating a random number between 0 and a specified maximum.
Typically a random number is produced with the following statement:

Since we access elements of an array with indices, we can generate a random index between 0 and the length of an array so to select a random element in it.
The first problem we have to solve is that random gives a "real" number (ex: 4.993319470244624, 1.9486631456631776, 7.1841821754535813, etc.) while the indices of an array are "integer" numbers (5, 2, 7, etc.). We thus need to round the "real" numbers produced by random (4.993319470244624 -> 5, 1.9486631456631776 -> 2, 7.1841821754535813 -> 7). We do this with the ```Math.floor``` function:
