Why it’s written this way
\b[A-Z]{2,}\b requires at least two consecutive uppercase letters bounded by word boundaries on both sides, so it fires only on a whole word that is entirely capitalized, not a word that merely starts with one.
The {2,} lower bound is deliberate: a single capital letter, like the start of an ordinary sentence or a lone initial, doesn't count as shouting.
Edge cases to know
- →It can't tell a genuine acronym like NDA or API from a sentence typed in all caps out of frustration — both look identical to the pattern.
- →A word like 'NASA2' or the plural 'FAQS' still matches on its uppercase run, since trailing digits and a lowercase-adjacent S sit outside what the pattern checks.
- →Single capital letters are excluded by design, so an initial such as the J in 'J. Smith' never triggers a false positive.
