Yes! Javascript supports automatic type conversion. You should take advantage of it, It is the most common way of type conversion used by Javascript developers.

JavaScript is a "loosely typed" language, which means that whenever an operator or statement is expecting a particular data-type, JavaScript will automatically convert the data to that type.

Example:

var s = '10';
var a = s*1;
var b = +s;
typeof(s); //"string"
typeof(a); //"number"
typeof(b); //"number"?
