Before I address that, it's important to note that ES6 module syntax is not the same thing as how Node.JS imports modules. Solve real world problems with OOP. The inverse of Math.expm1(). Anyways, Math.trunc is a simple alternative to Math.floor and Math.ceil where we simply discard the decimal part of a number. Another alternative that’s also quite useful is to use Babel’s online REPL – it’ll show you compiled ES5 code to the right of your ES6 code for quick comparison. Surprisingly, our handmade method is more precise than the native one (at least on Chrome 45) for this case in particular. Cool, and also probably the last time you’re going to see that method in use for the foreseeable future. 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. to our mailing list and be the first to know when new articles come out!
