…allback.js

…ork with just a return or in an if statement but not if it is spelled wrong XD

… scope to call the function within it that performs a closure by grabbing variables from the larger function

…ms names to a new item of another array called fullNames

… made another array to push to so that I could change the case before I pushed it to the proper array but saw in the documentation that I could use the method inline/on the value directly

…because I never gave it the parameter/reference the function would be looking at, I went straight into the property thinking i didn't need to

… filtered array

…row function

…gned some saved memory to the outcome of the method instead of pushing to it with a push method

…al number of the new array with reduce when all I needed was length

…r and indexOf

…was missing a return from my nested function
