javascript - Regex in JS to find first characters of each word and cast to Uppercase -

i looking regular look in javascript help me homecoming first characters of each word in uppercase:

"to string" => "tds"

most of import part homecoming new string old.

easy, 2 functions:

result = subject.replace(/\b[a-z]+\s*/g, "").touppercase();

in demo, @ substitutions @ bottom. that's effect of regex replacement before touppercase()

how works

\b matches position not word boundary, in other words, spot between 2 letters. [a-z]+ matches many letters possible \s* matches optional spaces we replace empty string we convert upper case
