Dart Computer Programming for Beginners: 04 Variables and Typing

variable – a letter or series of characters that stand for a different value
Declare – to make it known that it is a variable
Initializing a variable is giving a variable the first value
Dart is strong and optionally typed
Strong typing – a value will not ever change types
Weak typing- a value type may change, depending upon circumstances
Dynamic typing – variable can have different types

You can add 2 strings together to concatenate them, but you cannot subtract 2 strings.

I am super new to programming and luckily landed on these series. It is just PERFECT for a beginner like me. It hits the nail on what I was looking for: explanation of concepts. For real, THANKS.
