Node.js

Q1: What do you mean by Asynchronous API? ☆☆

Answer:
All APIs of Node.js library are aynchronous that is non-blocking. It essentially means a Node.js based server never waits for a API to return data. Server moves to next API after calling it and a notification mechanism of Events of Node.js helps server to get response from the previous API call.

let map = new Map();
map.set("a", 1);
map.set("b", 2);
map.set("c", 3);

let obj = Array.from(map).reduce((obj, [key, value]) => (
  Object.assign(obj, { [key]: value }) // Be careful! Maps can have non-String keys; object literals can't.
), {});

console.log(obj); // => { a: 1, b: 2, c: 3 }
