Recursive Functions

function countDwon(n){
if(n > 1){
countDwon(n -1) // recursive call
else {
return true // base case

How computers execute a recursive functions:

function sumUpTo(n){
if(n > 1){
sumUpTo(n - 1) + n
} else {
return 1

// this translates to
sumUpTo(4) + 5
// then
sumUpTo(3) + 4
sumUpTo(2) + 3
sumUpTo(1) + 2
// 1
