Answer 1

Yes, using the split method:

var str = "sample@email.com";
var res = str.split("@"); //An array, which looks like this [sample, email.com]

Answer 2

var email = foo@gmail.com
// variant 1 (without '@')
var mailArr = email.split('@');
var logn = mailArr[0];
var mailHost = mailArr[1];
// variant 2
var atPosition = email.indexOf('@');
var logn = email.slice(0, atPosition);
var mailHost = email.slice(atPosition, -1);

And for more common uses you should use regular expressions
