Regular Expression

This is more of a note-to-self type of post.

You know that series of symbols and characters in a chain following each other? Sometimes you will find them with a find, replace, or find and replace function.


  • This processes a URL:
  • somefunction.replace(/^http[s]{0,1}:\/\/[^\/]*\/?/, '/')

    #<!--.*?-->#s =>
    #\bsrc="/(favicon\..*)"# => src="http://mycdn.somewhere.com/$1"
