Ruby produce modified string from array

Question

I have an array

["http://www.google.com", "http://www.yahoo.com", "http://www.weather.com"]

and I would like to produce one long string

<a href="http://www.google.com">http://www.google.com</a>, <a href="http://www.yahoo.com">http://www.yahoo.com</a>, <a href="http://www.weather.com">http://www.weather.com</a>

I know I can write a for loop, and then append each element of the array to the long string twice. Is there a slicker way to do that?

You can do:

urls = ["http://www.google.com", "http://www.yahoo.com", "http://www.weather.com"]
urls.collect { |url| "<a href=\"#{url}\">#{url}</a>" }.join (', ')

This will give you:

"<a href=\"http://www.google.com\">http://www.google.com</a>, <a href=\"http://www.yahoo.com\">http://www.yahoo.com</a>, <a href=\"http://www.weather.com\">http://www.weather.com</a>"
