Question

How do you map the array values without using map method in Javascript?

Answer 1

You can map the array values without using the map method by just using the from method of Array. Let's map city names from Countries array,

const countries = [
  { name: "India", capital: "Delhi" },
  { name: "US", capital: "Washington" },
  { name: "Russia", capital: "Moscow" },
  { name: "Singapore", capital: "Singapore" },
  { name: "China", capital: "Beijing" },
  { name: "France", capital: "Paris" },
];

const cityNames = Array.from(countries, ({ capital }) => capital);
console.log(cityNames); // ['Delhi, 'Washington', 'Moscow', 'Singapore', 'Beijing', 'Paris']
