+# Advent of Code 2022 - Assignment3 javascript solution
+This problem is all about searching for duplicates in strings. The solution is implemented using slice to split the string in half.
+The priority is retrieved using the ASCII charcode character for convienence. How to retrieve inputs differs between part1 and 2, therefore a checkbox is provided to toggle between different parsing methods.
