for in: runs over an object's enumerable property names.
for of: (new in ES6) takes an object-specific iterator and loops through the data it generates.
Both the for..of and for..in commands iterate over lists, but the results they return are different: for..in returns a list of keys on the object being iterated, whereas for..of returns a list of values of the object's numeric attributes.
let arr = [3, 4, 5];
for (let i in arr) {
console.log(i); // "0", "1", "2",
}
for (let i of arr) {
console.log(i); // "3", "4", "5"
}
