How do you find the max value in an array using apply?
Math.max.apply(null, [1, 2, 3]) returns 3. In modern JS, use spread: Math.max(...[1, 2, 3]). Both work, but spread is more readable.

Use call: Array.prototype.slice.call(arguments) borrows slice to convert array-like objects to arrays. Array.prototype.forEach.call(nodeList, fn) borrows forEach for NodeLists.
Use bind: setTimeout(obj.method.bind(obj), 1000). Or use an arrow wrapper: setTimeout(() => obj.method(), 1000). bind permanently sets this for the returned function.
In the child constructor, call the parent constructor with this: Person.call(this, name). This borrows the parent constructor and sets properties on the child instance.
