Variables in Programming - Core Coding 3
This is part 3 of the Core Coding course - Variables in Programming.
We'll consider what variables are an how they work. We'll talk about the difference between variables and constants.
We'll then launch into a discussion on data types along with the differences between addition and concatenation. Javascript is known as a 'dynamically typed' language since it intelligently guesses at the type of data being stored. Many languages don't do this and are instead referred to as 'statically typed' programming languages.
We'll finish off by taking a look at some of the various mathematical operations that can be run using code.
