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}; 

I could write something like this :

 if(myObj.title && myObj.name && myObj.email){  /*Some code */ }; 

But I am looking for the simplest way to write it. eg :

if(myObj all is true){ /*Some code */ }; 

I might have another object with 10-20 items inside it, and will need to know if all are true.

With ES2017 Object.values() life's even simpler.

Object.values(yourTestObject).every(item => item) 

Even shorter version with Boolean() function [thanks to xab]

Object.values(yourTestObject).every(Boolean) 

Or with stricter true checks

Object.values(yourTestObject)     .every(item => item === true)
