I am having problems writing proper regex in javascript that matches specific word (for example "world") which is not substring, but can be followed by special characters. My closest solution was



 /bworldb/gi


which works fine, BUT what if that word is composed from special characters, for example "$$$"? In that case regex looks like this: 



/b$$$b/gi


but this expression matches word a$$$a, but doesn't match $$$ which is exactly opposite of what it was supposed to match.

  • /b$$$b/gi will match $$$ only when enclosed with word chars. Use /B$$$B/gi. A more generic soluon is here (in case your input is dynamic).
