Class and objects

morning challenge, counting vowels

class and object basics

looked very briefly at closure, need to look more into that

pointing to a variable

let x = null

let y = 10

x = y

think of variables as pointers to objects, when you assign directly to a variable, you are not modifying any objects you're merely repointing your variable to a different object

factory and constructor functions

.bind()

now moving on to using Class keyword

it just has a nicer clearer syntax that's similar to ruby

getters and setters is again just a sugar syntax

you can just write them as functions

then we did a quick challenge
