Iterate attributes in object

for-attribute-in-thing.js

let thing = { attr1: 'val1', attr2: 'val2' };

// Least nice
let keys = Object.keys(thing);
for(let i = 0; i < keys.length; i++) {
	console.log(thing[keys[i]]);
}

// Nicer
Object.keys(thing).forEach((attribute) => {
	console.log(thing[attribute]);
});

// Nicest
for(attribute in thing) {
   console.log(thing[attribute]);
}
