OK, so we're done with the second chapter.
Now you've seen the first two fundamentals of the column programming language, and we of course, have
a bunch more fundamentals to learn object oriented programming, but on more advanced stuff as well.
So in this chapter, what we have looked at are variables, so how we can store data.
Then we saw that there are different data types that we need to be careful with.
Then we looked at these statements and when statements, so code that will only be executed if a specific
condition is met.
And then also loops.
So code that will be rerun multiple times depending on conditions and also on how many times you want
it to run, or maybe even how many times it's supposed to run based on values that it has based on its
state.
And then we looked at functions which allow us to sum up code to be reused.
And this is super important and useful, and that book come in even more useful when we get back to
object oriented programming.
All right.
So then we also look at knuckleballs.
So how to use variables which have a null value, which are pretty much empty?
And what you need to consider when using them?
All right.
So that's it for this chapter.
I hope you also run through the exercises and to finish them.
And yeah, let's get right into the next chapter and where we're going to look at object oriented programming.
All right, so see you in the next chapter.
