javascript - lodash: check object is empty

Question

I have this object: {"": undefined}

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

I get false result, maybe in lodash we have another method?

Answer 1

_.isEmpty(obj, true)

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

console.log(_.isEmpty(obj)); // false
console.log(_.isEmpty({})); // true
