I'm looking to compare one paragraph of text to another and output any words that don't appear in the original paragraph. Both are similar but one has additional words written into it and I just need to output these extra words if that makes sense.

I know some javascript but I'm pretty unsure how to go about this. Guessing it would be along the lines of breaking the words down into strings and progressing from there... Or this may be much harder than I originally thought it might be.

Any help with the general code or pointers would be much appreciated!!

All the best,
Max
