Arrows in classes
class A { hi = () => { return 'Hi' + '!'; } bye = () => { return 'Bye' + '!'; } message = () => { return this.hi() + this.bye(); } } const a = new A(); const message = a.message; message();
Bind in classes
class A { constructor() { this.message = this.message.bind(this); } hi() { return 'Hi' + '!'; } bye() { return 'Bye' + '!'; } message() { return this.hi() + this.bye(); } } const a = new A(); const message = a.message; message();
Bind in classes prototype
class A { constructor() { this.message = A.prototype.message.bind(this); } hi() { return 'Hi' + '!'; } bye() { return 'Bye' + '!'; } message() { return this.hi() + this.bye(); } } const a = new A(); const message = a.message; message();
Mixed in classes
class A { hi() { return 'Hi' + '!'; } bye() { return 'Bye' + '!'; } message = () => { return this.hi() + this.bye(); } } const a = new A(); const message = a.message; message();
