Regex to get words between ":" and "," in javascript -

I'm learning regex. I am trying to get the most correct regex for:

is input:

  category: first, category: second, subject: math, subject: bio , Room: nine  

expected output:

  store first, second, math, bios, nine  

Want the above output in a string; var s = ""; Whatever I have tried here:

  (:) (. *) (,)  

However, I should also want the last word

< / Div>

Use:

  var again = /:(.*?) (: | $) / G; // `, | $ `: Match`,` or end of string Var str = 'class: first, category: second, subject: math, subject: bio, room: nine'; Var result = []; Match match; While ((match = re.x)! == faucet) results push (match [1]); result. Include (',') // = & gt; The use of 'first, second, math, bio, nine'.  

:

  var re = /: (. *?) (,) / G; Var str = 'class: first, category: second, subject: math, subject: bio, room: nine'; Str.match (re) .map (function (m) {return m.replace (/ [,:] / g, '');}). Join (',') // = & gt; 'First, second, math, bio, nine'
