check all data from object javascript

Question

hi guys I have an object like this

const tmp ={
    identityType:null,
    identityNumber:null,
    nationality:null,
    firstName:null,
    secondName:null,
    gender:null,
    birthDate:null,
    bornCountry:null,
    profession:null,
    province:null,
    city:null,
    address:null,
    postCode:null,
    img:null,
  };

can I check the tmp if all data is not null I will do something ?, I know the easy way just use if , but the data is too much if I'm using If operator ?

Answer 1

Use the every() method to test if all elements of an array fit some criteria. And Object.values() to get the values in the object as an array.

if (Object.values(tmp).every(el => el !== null)) {
    console.log("All values are not null");
}

Answer 2

If you want to check if all values are nulls just check if

Object.values(tmp).filter(el => el !== null).length === 0

The same for all falsey values (null, undefined, 0, etc.)

Object.values(tmp).filter(el => Boolean(el)).length === 0
