Js in bits - 8.2(basic operators)

Learning js should be fun. It is fun if it's easy.
I tried my best in writing this, to understand it the easy way.

String concat with binary +

The result is concatenation.

Concatenation of string with numbers converts numbers ---> strings.

But, there are some gotchas

String with other Math operators does math(convert string ---> number)

Leave y'r thoughts....
