let myVariable = 22; //this can be a string or number. let is block scoped

// write what ever you want
// one way is
// this is to declare intigers
var a = 10;
//this is to declare strings aka words
var b = "hi";
// the key word var can be replaced by let
//like this
let a = 10;
let b = "hi";
// i recomend using let insted of var

// let & var are both editable variables:
var cow = 'moo';
let pig = 'oink';
cow = 10;
pig = 10;
// const is a permanent variable; you cannot change it.
const uncuttableGrass = '\/\/';
uncuttableGrass = '___';
// above throws an error
