The Math.random() function returns a floating-point, pseudo-random number in the range 0 to less than 1 (inclusive of 0, but not 1) with approximately uniform distribution over that range — which you can then scale to your desired range. Base two logarithm of a number – log2(value). In ES6 you import … After all, it’s not like we stopped adding super-precise method names like Object.getOwnPropertySymbols(). Why trunc instead of truncate, then? Before I address that, it's important to note that ES6 module syntax is not the same thing as how Node.JS imports modules.
