00:00:00,180 --> 00:00:05,600
Javascript constants are values that are fixed for example in this script.

2
00:00:05,670 --> 00:00:13,960
We're adding two values 5 and 6 together and outputting the result in a paragraph with the I.D. math.

3
00:00:15,500 --> 00:00:23,480
The values that we're adding are fixed values 5 and 6 the value of these numbers is not dependent on

4
00:00:23,480 --> 00:00:24,990
any other factor.

5
00:00:25,340 --> 00:00:32,390
The 5 will always be 5 and the 6 will always be 6 unless we change them in the script.

6
00:00:34,340 --> 00:00:43,420
Let's preview this file to see the result in our web browser.

7
00:00:43,450 --> 00:00:45,790
Here we can see the Output result.

8
00:00:45,820 --> 00:00:46,330
Eleven

9
00:00:52,170 --> 00:01:00,680
constants can be in the form of numbers both whole and integer or strings strings are written within

10
00:01:00,680 --> 00:01:05,510
double or single quotes.

11
00:01:05,800 --> 00:01:16,420
We'll go ahead and change one of these values to a string.

12
00:01:16,490 --> 00:01:29,040
Now when we save the file and reload our web browser we can now see that my text is joined with the

13
00:01:29,040 --> 00:01:30,060
value 6.
