  "base": "USD",
  "rates": {
    "AED": 3.673027,
    "AFN": 68.475,
    "ALL": 123.095199,
    "AMD": 476.8075,
    "ANG": 1.78385,
    "AOA": 165.846832,
    "ARS": 15.05143,
    "AUD": 1.333463,
    "AWG": 1.793333,

How can I map this to muliple objects in typescript like this:

export interface Stock {
  name: string;
  value: number;
}

Thanks

Answer 1

let keys = Object.keys(data.rates);
let mapped: Stock[] = keys.map(key => {
    return { name:key, value: data.rates[key] } as Stock
});

console.log(mapped);

Answer 2

You donot need to map manually. Your Typescript code can be:

export interface Stock{
  timestamp : Number,
  base : String,
  rates : Rates
}

export class Rates{
  AED : Number,
 ..... so on
