Hi guys! I have a little problem:
https://pastebin.com/aZLuQkVe
this code would have to find in the textarea a word that I write in the input, and after finding it, the code must highlight the first letter. So I put paragraph.setSelectionRange(indexOfFirst); in this way it would have to highlight the letter corresponding to "indexOfFirst" number, but it doesn't work.
Maybe "indexOfFirst" is not took as number, but I tried to use Number(indexOfFirst) to convert it to number, but nothing changed.
Can you help me?
