Constructing Javascript Objects


I am building a simple model class in Typescript/Javascript and was wondering if there was a shorthand way to avoid having to explicitly set each property name based on the constructor arguments.

I found exactly what I was looking for. This is a Typescript feature only, so it wouldn’t work in pure Javascript, but it is much easier to type:

class Something {
  constructor(public prop1: string, public prop2: string) {}

than to type:

class Something {
  public prop1: string;
  public prop2: string;
  constructor(prop1: string, prop2: string) {
    this.prop1 = prop1;
    this.prop2 = prop2;

Both produce the same Javascript in the end.
