entries in javascript code example

Example 1: javascript convert Object.entries back to object

const arr = [ ['0', 'a'], ['1', 'b'], ['2', 'c'] ];
const obj = Object.fromEntries(arr);
console.log(obj); // { 0: "a", 1: "b", 2: "c" }

Example 2: js entries

const object1 = { a: 'somestring', b: 42 };
for (const [key, value] of Object.entries(object1)) {
  console.log(`${key}: ${value}`);
} // expected output: "a: somestring" "b: 42" order is not guaranteed
