IF IF statement with a Ternary (JavaScript)

Question

How can I turn the following statement into a Ternary.

if($.isNumber(arg1))
{
    if($.isNumber(arg2))
    {
        // something
    }
}

I know how to do an IF / ELSE with a Ternary statement like:

var a = $.isNumber(arg1) ? arg1 : $.isNumber(arg2) ? arg2 : undefined

for example.

not sure how to do an IF / IF / ELSE though.

Any help?

Answer 1

var a = $.isNumber(arg1) && $.isNumber(arg2) ? "something" : "nothing";
