Javascript REGEX : Tags

Question

I want to convert words into tags.

So for example I have an input, if I type in in this

apple, windows, stackoverflow, google, microsoft

then I will get this:

apple windows stackoverflow google microsoft

Delimiters should be space, semicolon, or comma, just like in stackoverflow :)

You can use the split method to split a string into an array, like this:

var tags = str.split(/\s*[ ,;]\s*/);

hmmmmm, looks cool, I've tested it here regex.larsolavtorvik.com but why are there commas after each word? is it because of the array? and what are the * sry I'm new in regex

The split function returns an array.

The * means to match zero or more of the previous item. \s means any (single) whitespace character.
