Script Preparation code:

var testObject = {
  a: "1",
  b: "2",
  c: "3",
  d: "4",
  e: "5",
  f: "6",
  g: "7",
  h: "8",
  i: "9",
  j: "10"
};

Tests:

Use Map and Object entries
var result = new Map(Object.entries(testObject));
Use cycle with copy of object
var result = new Map(); $.each(JSON.parse(JSON.stringify(testObject)), function (key, value) { result.set(key, value); });
