1 00:00:00,540 --> 00:00:01,740 Hello and welcome. 2 00:00:01,740 --> 00:00:12,110 In this fit you are be introducing you to the javascript logical operators javascript logical operators 3 00:00:12,310 --> 00:00:19,780 who are used to determine the logic between variables or values. 4 00:00:20,290 --> 00:00:26,150 So this is a basic table chores due to logical operators. 5 00:00:26,160 --> 00:00:33,510 The first is called The Ant and is represented by the assigned symbol. 6 00:00:33,900 --> 00:00:39,080 What that does it checks if all the conditions are met. 7 00:00:39,390 --> 00:00:43,100 And it will return boolean result. 8 00:00:43,170 --> 00:00:45,230 Either true or false. 9 00:00:45,300 --> 00:00:49,460 If all the conditions are met it will return true. 10 00:00:49,590 --> 00:00:52,360 If not Ireton is false. 11 00:00:52,410 --> 00:00:58,700 The links is the OR operator which is represented by the pipe symbol. 12 00:00:58,710 --> 00:01:07,190 He checks if any condition has been met and it will return a true boolean result. 13 00:01:07,260 --> 00:01:15,270 So the key distinction between the and the or is that when are using it and to check conditions or the 14 00:01:15,270 --> 00:01:24,000 conditions has to evaluate to true if they are not met then it will return false Boolean result unresolved 15 00:01:24,000 --> 00:01:28,620 bisk remains true or false in the operator. 16 00:01:28,800 --> 00:01:31,820 You only have to satisfy one condition. 17 00:01:31,890 --> 00:01:35,440 It will return true result. 18 00:01:35,490 --> 00:01:42,860 So let me quickly illustrate how the logical operators are used in the console. 19 00:01:43,050 --> 00:01:49,430 So I'm going to start by creating a couple of variables with variable X.. 20 00:01:49,650 --> 00:01:53,700 I give it a value of 7. 21 00:01:54,000 --> 00:01:56,710 Great are not a variable. 22 00:01:56,910 --> 00:02:11,370 When a call is variable y and I give it a value of 6 now I can use the logical operators to check the 23 00:02:11,370 --> 00:02:18,410 condition so I can see X is less than 10. 24 00:02:18,420 --> 00:02:35,370 If X is less than 10 and Y is greater than 6 this will evaluate to be false because the first condition 25 00:02:35,370 --> 00:02:36,260 is true. 26 00:02:36,600 --> 00:02:45,960 X is less than 10 but the second condition is false because Y is not greater than 6 so it would evaluate 27 00:02:46,320 --> 00:02:48,050 to be false. 28 00:02:48,360 --> 00:02:57,450 So if I use the OR operator with the same condition it will return true because one part of the condition 29 00:02:57,870 --> 00:02:58,610 is true. 30 00:02:58,830 --> 00:03:01,060 So it will return everything as true. 31 00:03:01,080 --> 00:03:16,530 For example the same illustration if I come in and say X is less than 10 or Y is greater than 6. 32 00:03:16,530 --> 00:03:24,480 This will evaluate to be true because the first part of the condition is true X is less than 10. 33 00:03:24,750 --> 00:03:32,730 So that's basically how you use a logical operator in a nutshell. 34 00:03:32,730 --> 00:03:41,730 Once you understand this basic use of it then it will be able to make more sense when you start using 35 00:03:41,730 --> 00:03:43,030 it later. 36 00:03:43,350 --> 00:03:45,490 Thank you for watching and bye for now.
