Hi I am having trouble understanding the second solution to the challenge, I was wondering if someone could explain every sentence in the code, and tell how does item fit in exactly in the code
/ As a function declaration AND using named function w/ a loop:*/
function justCoolStuff(firstArray, secondArray) {
function isInSecondArray(item){
for(let i = 0; i<secondArray.length; i++){
if (secondArray[i] === item){
return true
}
}
return false
}
return firstArray.filter(isInSecondArray)
}
