  Untechnically speaking: Arrow functions preserve the `this` in their declaration point, whereas regular functions change `this` if they're called as methods. class Foo { thisCouldBeAnything() {return this} thisIsDefinitelyFoo = () => this } new Foo().thisCouldBeAnything.call('use me') // 'use me' new Foo().thisIsDefinitelyFoo.call('unused') // Foo Since the intention is often to keep `this` to refer to the class, people have been binding every single method in the class constructor, but this is no longer necessary thanks to arrow functions.
