How to read space separated key of an object in JavaScript

Question

Help would be appreciated,to read key from an object, the key is separated with space

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

console.log(obj.student class) ? throws error.
console.log(obj.student roll) ? throws error.

The real question is why you should have spaces in your keys! — oiledCode

and not using quotes if you have not allowed character is an error, like spaces for instance — oiledCode

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']);

There are two way to read fields within the object

object.field
object[field]

To access fields having spaces you have to use second option

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