匹配大写单词的正则表达式，javascript 中有一些例外

Question

Consider the following strings which would match:

• HELLO WORLD HOW ARE YOU?
• HELLO world HOW are YOU?
• I am a SERIES OF WORDS that are capital
• I am INVALID.

While these would not match:

• Hello TV // (tv is not a word)
• Come to my BBQ at my 1200 SQ.FT House.

The rule is very simple: No all capital words. (abbreviations are fine, words are not)

Currently I have:

^(?!.*\b[A-Z]{2,}\b).*$

this is the closest question but it is almost opposite of what I am trying to do.

I am not good with regex at all, I have tried various online tools and this is as close as I got. I believe the issue lies with the fact it should be something like \w or \W as I want words, not individual characters and not abbreviations like TV, BBQ, SQ.FT and so on, they have to be full on words as indicated above.

Answer 1

Regular Expressions on their own cannot do this. You would need a separate dictionary with a list of all words that you do not want to be matched, then rule them out afterwards.
