Lodash: object check is empty

Question

I have this object: {"": undefined}

and when I check this object is empty: _.isEmpty({"": undefined})

I get the result false, maybe there is another method in lodash?

Answer 1

Your sample object is not empty, so instead you want to check if all the properties are undefined

let o = {foo: undefined};
!_.values(o).some(x => x !== undefined); // true

Answer 2

_.isEmpty(obj, true)

var obj = {
  'firstName': undefined
, 'lastName' : undefined
};

console.log(_.isEmpty(obj)); // false
