A simple wrapper around Math.random for returning a random boolean, with the
provided chance of being true. It exports an object with a ::get method to
facilitate stubbing for unit tests.
const boolChance = require('bool-chance');
let bool = boolChance.get(0.75); // Will return true 75% of the time.
let otherBool = boolChance.get(0.5); // Will return true half of the time.Even though this is very simple, popular utility libraries like
lodash don't have a method like it.
Chance.js does, but its api requires you to construct
an instance of a directly exported class, which can be frustrating for unit
tests since you can't stub the constructor. You can stub the Chance::Chance
method to get an instance, though having to do this every time you need to test
a random bool is annoying.
As a result, I found myself writing utility functions like this one in a lot of my personal projects. I figured I'd save myself some trouble and just publish it. Use if you like, though I don't really have plans to add much more to it in the future.
