Use arrow functions
ECMAScript 6 introduced arrow functions, which can be thought of as lambda functions. They don't have their own this
binding. Instead, this
is looked up in scope just like a normal variable. That means you don't have to call .bind
. That's not the only special behavior they have, please refer to the MDN documentation for more information.
function MyConstructor(data, transport) {
this.data = data;
transport.on('data', () => alert(this.data));
}
