fortnite chapter 4 scraper

#fortnitechapter4

notes

only searchs alphabet (A-Z) and does not include numbers or other special symbols: https://en.wikipedia.org/wiki/ASCII#Character_set

instructions

1. navigate to https://www.fortnitechapter4.com/
2. copy/paste individual functions
3. run search (can modify start of array and set number)
4. check localstorage in the developer tool section. codes are prefixed with code- so search is a bit easier
