Random JS

Random JS is a library I made to replace the annoying predefined version of random things in JavaScript.
Now, in order to use Random JS you need to either download it (click here) or include this in your script tag:

Example:

var rand = Math.floor(Math.random() * 7)

That's the annoying way to get a random number from 0 to 6. Now with my library, the code is as following:

var rand = random(6)

That gives the same result as the code above, but I have to write a lot less code!

Now, let's take a look at another useful feature, picking random elements from an array.

var arr = ["Jeffrey","Josh","John"]
var sel = selectRandom(arr)

Now "sel" will be either John, Josh or Jeffrey.

Let's have a look at the structure of these two functions.
random(to, from, step)
to: larges possible number
from: smalles possible number
step: steps (e.g has to be divisible by two, step will be two).

selectRandom(array, amount, unique)
array: the array to pick from
amount: amount of elements to be picked
unique: (boolean) each element should appear only once in the returned value, or not.
