I have an object:

const obj = {
    name: "",
    age: null
}

How can I check if all attributes is null or "" with lodash ? Is so, return true, if some attributes is not null or "" then false.

Reset to default 6

With lodash you can use _.every() to check if all properties are empty:

const obj = {
  name: '',
  age: null
}

const result = _.every(obj, v => v === '' || _.isNull(v))

console.log(result)
<script src="https://cdnjs.cloudflare./ajax/libs/lodash.js/4.17.15/lodash.js"></script>

You could use Object.values, Array.every and Array.includes:

const obj1 = { name: "", age: null }
const obj2 = { name: "", age: null, b: 0 }
const obj3 = { name: "", age: null, b: NaN }
const obj4 = { name: "", age: null, b: false }
const obj5 = { name: "", age: null, b: undefined }

function checkEmptyOrNull(obj) {
  return Object.values(obj).every(v => ['', null].includes(v))
}

console.log(checkEmptyOrNull(obj1))
console.log(checkEmptyOrNull(obj2))
console.log(checkEmptyOrNull(obj3))
console.log(checkEmptyOrNull(obj4))
console.log(checkEmptyOrNull(obj5))
