Determining if all attributes on a javascript object are null or an empty string

Question

What is the most elegant way to determine if all attributes in a javascript object are either null or the empty string? It should work for an arbitrary number of attributes

Answer 1

Edit: As user @abd995 noted in the comments, using Array.some() is more efficiënt as it stops the loop when the condition is met:

const isEmpty = !Object.values(object).some(x => (x !== null && x !== ''));

Original: 2017 answer: Check all values with Object.values(). Returns an array with the values which you can check with Array.every() or Array.some()... etc.

const isEmpty = Object.values(object).every(x => (x === null || x === ''));

• MDN Object.values()
• MDN Array.every()
