Now that nodejs/node#3072 is mostly fixed, we can finally start using Node 4+ features. This refactor: - uses arrow functions where appropriate Note that arrow functions still aren't used in Mocha, where `this` is sometimes meaningful. This also removes the need for .bind() nearly everywhere, as well as the `self = this` trick. - refactors Validator and Connection into ES6 classes - no longer uses Array#forEach for iterating arrays We strongly prefer for (let i = 0; i < arr.length; i++) because of performance reasons. Most forEaches have been replaced with for..of, though, which is 5x slower than the long-form loop but 2x faster than forEach, which is good enough outside of most inner loops. The only exception is tournaments, which is due for a more invasive refactor soon anyway.
