Callback functions are a little bit tricky to understand at first, but basically it let's you pass a function into another function as a parameter. The function you pass in gets then called from inside the function called.

function doCallBack(cb){
cb()
}

doCallBack(()=>{
console.log("i got called from within doCallBack")
})
