Function Challenge
1:24In this practice challenge, you will make the random number function you created earlier more flexible.
Now that you've learned how to define and
0:00
use functions,
I have a practice challenge for you.
0:02
I'd like you to make the random
number function you created earlier
0:05
even more flexible.
0:08
This time,
the function needs to accept two values,
0:10
a lower value and an upper value.
0:13
In other words, the function should be
able to produce random values between,
0:15
say, 10 and 100, or 9 and 78, as well
as between 1 and 6, or even 0 and 6.
0:19
Let's go over the steps for
this challenge.
0:25
To get started with this challenge,
launch the workspace with this video and
0:27
open the file random.js.
0:31
In the file, I've included
a comment that provides a high
0:34
level overview of the components of
the function you'll need to create.
0:37
I also provided the formula, or logic, for
0:41
creating a random value
between two numbers, 1 and 6.
0:43
This should look familiar,
0:47
you used this in a previous
course on JavaScript numbers.
0:48
Now, you're going to use this as
the basis for creating the function for
0:50
this challenge.
0:54
Your function should be able to produce
random values between, say, 10 and
0:55
100, or 9 and 78, as well as between 1 and
6, or even 0 and 6.
1:01
Once you're done writing the function,
make sure you test it by calling it and
1:05
passing it different values.
1:09
You can display the values
in any way you choose.
1:11
For example, in the console with
console.log, and in alert dialogue or
1:13
on the page using some of
the techniques you've learned so far.
1:17
So good luck, and in the next video,
I'll show you my solution.
