There are two way to read fields within the object

  1. object.field
  2. object[field]

To access fields having spaces you have to use second option

console.log(Obj['student class']); console.log(Obj['student roll']);

Put it in quotes and use bracket notation.

var Obj = {
  'student class': '4th',
  'student roll': '24'
};

console.log(Obj['student class']);
console.log(Obj['student roll']);
