Question

I didn\'t get an optimized regex that split me a String basing into the first white space occurrence:

var str=\"72 tocirah sneab\";

Just split the string into an array and glue the parts you need together. This approach is very flexible, it works in many situations and it is easy to reason about. Plus you only need one function call.

arr = str.split(' ');             // ["72", "tocirah", "sneab"]
strA = arr[0];                    // "72"
strB = arr[1] + ' ' + arr[2];     // "tocirah sneab"

Alternatively, if you want to cherry-pick what you need directly from the string you could do something like this:

strA = str.split(' ')[0];                    // "72";
strB = str.slice(strA.length + 1);           // "tocirah sneab"

Or like this:

strA = str.split(' ')[0];                    // "72";
strB = str.split(' ').splice(1).join(' ');   // "tocirah sneab"

However I suggest the first example.
