// RECOMMENDED TYPE-SAFE APPRORACH
// View the bottom for the unsafe approrach

// to add a property, create a type for the object
// add the property that you want to be added
// make it optional (property?: type)
// 							 ^

type MyObject = {
  property: string;
  property2?: string;
}

const myObject: MyObject = {
  property: 'value'
};

myObject.property2 = 'value2';

// Method without types
// Hint: you can change the type from 'any' to another type
// only do this if all values are of the same type!
const myObject: {[key: string]: any} = {
    property: 'value'
};

myObject.property2 = 'value2';
