That expression is similar to split('')

you have no shame if you ask this under this solution.

w.o running the code, it's probably b.c you didn't split the, into characters and kept them and full strings.... but I'm still pretty new at coding.

you cant use a + on strings, you need to concat

Also, this is an inefficient solution. Try to avoid nested for loops where possible, as this can cause critical performance issues. This is especially the case with big data sets.

map returns whatever you return

It does work, any test/s not passing?

argument has a different name - you should change array.length to A.length
