Type Conversion:

A litle note about converting from one data type to another in JavaScript:

What happens if you add a "string" to a boolean, Number or another "string"?

1. "string" + boolean:

JavaScript assumes that the boolean should be converted to a "string". Once done so, the two are concatenated.

2. "string" + Number:

JavaScript assumes that the Number should be converted to a "string". Once done so, the two are concatenated.

3. Boolean * Number:

JavaScript assumes that the boolean should be converted to a Number. Once done so, the two are mathematically operated upon.

4. "string" * Number:

JavaScript cannot be mathematically operated on by Numbers, thus we have NaN.
