How to know if all javascript object values are true?

Question

In JavaScript, I need to know if all object items are set to true.

If I have the following object:

var myObj = {title:true, name:true, email:false};
         


        

Answer 1

In modern browsers:

var allTrue = Object.keys(myObj).every(function(k){ return myObj[k] });

A shorter alternative to this is:

var allTrue = myObj.every(function(i) { return i; });

If you really want to check for true rather than just a truthy value:

var allTrue = Object.keys(myObj).every(function(k){ return myObj[k] === true });
