Summary

That brings us to the end of Section 2.

Let's have a quick reminder of what we have covered so far.

First of all, we made sure we understood what types are, and then we had a really good look at the scalar types: the fundamental types that form the basis of all of our data. We learned about the four different ways we can create strings and illustrated some of the pros and cons of each. We had a very brief look at some string functions, though I encourage you to really go back to the docs and see how many there are. We looked at ints and floats, and explained how floats can catch you out. And, of course, we touched on bools; there's not much to say about them other than that they are great.

After this exploration of scalars, we moved on to looking at type juggling and comparison. We looked at the difference between equality and identity when comparing things. We confirmed that the rules around type juggling are predictable but often complex and ideally should...
