Find the largest number from a string using a regular expression

Question

I have a variable string like:

var myString = "857nano620348splitted3412674relation5305743"; 

How do I find the largest number from this?

I have tried like the below without any success.

var matches = myString.match(/d+/g); 

Answer 1

I'd go for

var myString = "857nano620348splitted3412674relation5305743"; var largest  = Math.max.apply(null, myString.match(/\d+/g)); 

FIDDLE

myString.match(/\d+/g) returns an array of the numbers, and using Math.max.apply(scope, array) returns the largest number in that array.
