angular & typescript constructors

Constructors in TypeScript

• when constructing objects in typescript, you can use a similar java-esque convention by creating the properties on the object and then intializing them in the constructor, like below:

  export class Ingredient {
    public name: string;
    public amount: number;
  
      constructor(name: string, amount: number) {
        this.name = name;
        this.amount = amount;
      }
  }
  
  

• or you can prefix the property names in the constructor with public or private and it automatically creates the properties for you! yay for less code!

   export class Ingredient {
       constructor(public name: string, public amount: number) {}
   }
