myObj.hasOwnProperty('key') // it checks object for particular key and not on prototypejs does object contain value
// You can turn the values of an Object into an array.
// Then test that a value is present:
// This assumes, that the Object is not nested
// and the value is an exact match:
var obj = { a: 'test1', b: 'test2' };
// Note that an array can only have positive index's; so
// checking for a negative index is a super valid way for getting a
// boolean value as a result for the check.
if (Object.values(obj).indexOf('test1') > -1) {
console.log('Value exists!');
