In ruby, I often use something like this:

if "my string123" =~ /string(\d+)/
  puts "I got #{$1}"
end

How would I do something similar in javascript? Currently, I’ve been doing this but it feels dirty.

m = "my string123".match(/string(\d+)/)
if (m)
  puts "I got " + m[1]

Perhaps I should just live with this, but thought I’d ask if there was a syntax subtelty I was missing. Thanks!

    You aren’t missing anything.
    If m is already defined, you could do if(m = "string".match(/regex/)), but this is less clean anyway, and you cannot use that with var.
