00:00:00,120 --> 00:00:04,550
In JavaScript the equals sign is an assignment operator.

2
00:00:04,560 --> 00:00:06,840
This sounds more confusing than it is.

3
00:00:06,960 --> 00:00:14,400
It just means that the value of the left upper end is equal to the right upper end in the equation x

4
00:00:14,430 --> 00:00:20,180
equals Y equals sine assigns the value of y to X..

5
00:00:20,400 --> 00:00:27,150
This is important because it allows us to compute values of two different data types such as numbers

6
00:00:27,270 --> 00:00:28,850
and strings.

7
00:00:28,860 --> 00:00:30,240
Let's take a look at an example

8
00:00:35,640 --> 00:00:44,910
in this javascript code we're adding a numerical value with a text string.

9
00:00:45,270 --> 00:00:49,680
If we save the file and preview it in our web browser

10
00:00:55,980 --> 00:01:03,650
we can see that the numerical value 30 is attached to the text string.

11
00:01:03,670 --> 00:01:04,170
That's.
