Which Unix command to get a number from inside this string?

Question

I'd like to hear your suggestions about collecting from this string (which returned by a command) the value which is next to result (In this case 15) :

{
    "outcome" => "success",
    "result" => 15
}

Which utility/command to do suggest me ? Thanks Max
