The Longest Word in a String

Tell us what’s happening:

Hey guys, i find Basic Algorithm Scripting exercises very difficult, i only did Basic JS and Object Oriented and Functional Programming tutorials. Do i need more knowledge from elsewhere to be able to do the Algorithm exercises? the tools for the answers in the exercises used are things that i dont remember learning in the previous courses.
