1
00:00:00,240 --> 00:00:04,220
The arrow functions we've written so
far have had no arguments.

2
00:00:04,220 --> 00:00:07,060
What do they look like
if there are arguments?

3
00:00:07,060 --> 00:00:07,980
Let me show you.

4
00:00:07,980 --> 00:00:11,530
First, let's create arrow functions
that take a single argument.

5
00:00:12,700 --> 00:00:15,317
Open up the second JavaScript file and

6
00:00:15,317 --> 00:00:19,470
we're going to modify
the functions square and cube.

7
00:00:19,470 --> 00:00:24,429
For each function, let's set up variables

8
00:00:24,429 --> 00:00:29,074
with appropriate names, square, And cube.

9
00:00:32,756 --> 00:00:38,450
Next, remove the function keyword and
each of the function's names.

10
00:00:41,435 --> 00:00:44,440
Finally, add arrows to
each of the functions.

11
00:00:47,875 --> 00:00:48,868
As you can see,

12
00:00:48,868 --> 00:00:53,700
the syntax is exactly the same with
a single argument as with no arguments.

13
00:00:56,903 --> 00:01:02,190
Let's see what an arrow function
looks like with multiple arguments.

14
00:01:02,190 --> 00:01:08,260
Open up the third file and let's convert
multiply into an arrow function.

15
00:01:08,260 --> 00:01:12,740
Start by assigning the function
to a multiply constant variable.

16
00:01:16,327 --> 00:01:19,960
Then, remove the function keyword and
the function name.

17
00:01:22,292 --> 00:01:23,780
Finally, add the arrow.

18
00:01:25,430 --> 00:01:31,888
There's also add and subtract here, these
need to be converted to arrow syntax too.

19
00:01:31,888 --> 00:01:34,390
Why don't you convert these for practice?

20
00:01:34,390 --> 00:01:35,330
In the next video,

21
00:01:35,330 --> 00:01:39,830
we'll take a look at an even more
concise way to write arrow functions.
