1 00:00:00,580 --> 00:00:07,620 Comparison operators are used to compare the equality or difference between variables or values. 2 00:00:07,630 --> 00:00:11,890 There are several comparison operators that can be used in JavaScript. 3 00:00:11,890 --> 00:00:19,010 This chart provides an overview of each one will go through a few of them to demonstrate how they work 4 00:00:20,210 --> 00:00:21,360 in this test script. 5 00:00:21,380 --> 00:00:29,110 We've created a variable and assigned it a value of six we'll use the get element by idea method to 6 00:00:29,110 --> 00:00:36,190 output a true or false result when using different comparison operators to compare our variable value 7 00:00:37,060 --> 00:00:37,950 with another value. 8 00:00:39,720 --> 00:00:49,190 Let's start with our equal to operator let's test to see if our variable value is equal to 8. 9 00:00:49,220 --> 00:00:50,830 We know that this is not the case. 10 00:00:51,500 --> 00:00:59,270 So our script should output the word false when we tested in our web browser so save this file and just 11 00:00:59,270 --> 00:01:00,340 tested in the browser. 12 00:01:02,230 --> 00:01:06,910 And we can see that it does in fact output the word false. 13 00:01:09,860 --> 00:01:12,020 If we were to change the value to 6 14 00:01:15,430 --> 00:01:25,830 then and refresh our web browser the output is true because our variable value x is in fact equal to 15 00:01:25,830 --> 00:01:26,340 16 00:01:31,940 --> 00:01:47,170 we can use the not equal operator to see if our variable is not equal to 10 for example. 17 00:01:47,210 --> 00:01:51,450 This is the symbol for not equal will update the six to 10 18 00:01:54,480 --> 00:02:03,720 so we know that our variable value 6 is not equal to 10 so when we test this in our web browser it should 19 00:02:03,720 --> 00:02:07,770 display true which it does. 20 00:02:07,930 --> 00:02:09,640 Now if we were to change this to 6 21 00:02:12,300 --> 00:02:21,160 it should display false because our variable value is in fact equal to 6. 22 00:02:21,230 --> 00:02:25,370 You can test out the remaining comparison operators and see what the outcome produces.
