Declare block scope variables with let

You're using var to declare variables within a block:

var i, max = 10;

for (i = 0; i < max; i++) {
    var timesLooped = i + 1;
    console.log('Times looped:', timesLooped);
}

Use ES6 let instead:

var i, max = 10;

for (i = 0; i < max; i++) {
    let timesLooped = i + 1;
    console.log('Times looped:', timesLooped);
}
