Javascript object conversions

String to object

const obj = JSON.parse('{"name":"John", "age":30, "city":"New York"}');

Copy object (not just put another pointer to it)

let newObj = JSON.parse(JSON.stringify(obj));

Sort object by key, capitalized letters will go first.

var data=Object.entries(query2).sort();

Copy an object, put all keys to lowercase

const newObj = Object.fromEntries(
  Object.entries(obj).map(([k, v]) => [k.toLowerCase(), v])

Iterate through an object

const object1 = {
  a: 'somestring',
  b: 42

for (const [key, value] of Object.entries(object1)) {
  console.log(`${key}: ${value}`);

Object to array:

const arr = Object.entries(obj);
