Welcome to this lesson.
00:02
In this lesson we have defined a func which is a function that takes in arguments a and b and returns a times 2 of r sub b.
00:15
So we assume that the a func is the one you want to define above.
00:21
We are looking at which of them will result in an error.
00:23
So let's comment the first one.
00:27
Let me clear my console.
00:53
So the first one runs without an error.
00:59
So let's move to the second one.
01:02
So let me comment this.
01:06
Then i will comment this part.
01:13
So this one says the a func makes into position arguments a and b.
01:35
So the b part returns an error.
01:39
So it is for us to be sure that this is only the b part...
