Answer 1

WELCOME TO 2020 *Drools in ES6*

Theres some pretty old answers in here - take advantage of destructuring. In my opinion this is without a doubt the nicest (very readable) way to iterate an object.

Object.entries(myObject).forEach(([k,v]) => {
    console.log("The key: ",k)
    console.log("The value: ",v)
})

Answer 2

I think the fast and easy way is

Object.entries(event).forEach(k => {
    console.log("properties ... ", k[0], k[1]); });

just check the documentation https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/entries

Answer 3

You can use below script.

var obj={1:"a",2:"b",c:"3"};
for (var x=Object.keys(obj),i=0;i<x.length,key=x[i],value=obj[key];i++){
    console.log(key,value);
}

outputs
1 a
2 b
c 3

Try this:

var value;
for (var key in dictionary) {
    value = dictionary[key];
    // your code here...
}
