Alternative version for Object.values()

Since Object is a (not so) recent implementation, if you want to support all browsers (AKA IE11 and below), then you need to create your own function:

function objectValues(obj) {
    var res = [];
    for (var i in obj) {
        if (Object.prototype.hasOwnProperty.call(obj, i)) {
            res.push(obj[i]);
        }
    }
    return res;
}

You can also modify this for Object.keys() and Object.entries() easily.

PS: Just noticed the ecmascript-6 tag. Btw I keep this answer here, just in case someone needs it.

Object.values() is part of the ES8(June 2017) specification. Using Cordova, I realized Android 5.0 Webview doesn't support it. So, I did the following, creating the polyfill function only if the feature is not supported:

if (!Object.values) Object.values = o=>Object.keys(o).map(k=>o[k]);

You can get array of keys with Object.keys() and then use map() to get values.

var obj = { foo: 'bar', baz: 42 };
var values = Object.keys(obj).map(function(e) {
  return obj[e]
})

console.log(values)

With ES6 you can write this in one line using arrow-functions.

var values = Object.keys(obj).map(e => obj[e])
