I want to concatenate a couple of variables with unknown types in a string

concatenation with pluses might lead to unexpected results, In fact I want to get the result 123 

var one = 1;
var two = 2;
var three = '3';
var result = one + two + three;
alert(result);//I want-> 123

+'' will cast it to string

Try this:

var one = 1;
var two = 2;
var three = '3';
var result = one + '' + two + '' + three;
alert(result);
