Answer 1

In lodash, you can use _.some

_.some(props.something, _.isEmpty)

Answer 2

You can use lodash _.every and check if _.values are _.isEmpty

const profile = {
  name: 'John',
  age: ''
};

const emptyProfile = _.values(profile).every(_.isEmpty);

console.log(emptyProfile); // returns false

Answer 3

Possible ways:

Iterate all the keys and check the value:

let obj = {a:0, b:2, c: undefined};

let isEmpty = false;

Object.keys(obj).forEach(key => {
    if(obj[key] == undefined)
        isEmpty = true;
})

console.log('isEmpty: ', isEmpty);

Use Array.prototype.some(), like this:

let obj = {a:0, b:1, c: undefined};

let isEmpty = Object.values(obj).some(el => el == undefined);

console.log('isEmpty: ', isEmpty);

Check the index of undefined and null:

let obj = {a:1, b:2, c: undefined};

let isEmpty = Object.values(obj).indexOf(undefined) >= 0;

console.log('isEmpty: ', isEmpty);
