This project checks that all the tags in a given piece of text (a paragraph) are correctly nested, and that there are no missing or extra tags. An opening tag for this problem is enclosed by angle brackets, and contains exactly one upper case letter, for example <T>, <X>, <S>. The corresponding closing tag will be the same letter preceded by the symbol /; for the examples above these would be </T>, </X>, </S>.

Run the example file

npm run start

Run the unit tests
