I have a Javascript object like:

How to remove all the undefined properties? False

Answer 1

I would use underscore and take care of empty strings too:

var my_object = { a:undefined, b:2, c:4, d:undefined, k: null, p: false, s: '', z: 0 };

var result =_.omit(my_object, function(value) {
  return _.isUndefined(value) || _.isNull(value) || value === '';
});

console.log(result); //Object {b: 2, c: 4, p: false, z: 0}
