1 00:00:00,610 --> 00:00:03,810 Hell they are welcome in this video. 2 00:00:03,810 --> 00:00:10,300 I will be explaining some of the javascript operators. 3 00:00:10,350 --> 00:00:21,420 I will begin with the three men big operators the operators you would use if you were to perform a map 4 00:00:21,510 --> 00:00:25,980 mapping called Operation or calculation. 5 00:00:25,980 --> 00:00:26,690 All right. 6 00:00:26,700 --> 00:00:29,130 I've got a little table here. 7 00:00:29,130 --> 00:00:35,670 All right so these are symbols and these are the description so we begin with the first one which is 8 00:00:36,420 --> 00:00:38,340 the symbol is sent to Shen. 9 00:00:38,370 --> 00:00:40,400 I'm sure you saw him in war before. 10 00:00:40,410 --> 00:00:42,040 It looks like a cross. 11 00:00:42,290 --> 00:00:52,500 And this is an addition of concatenation when the same ball is used with text it's known that concatenations 12 00:00:52,500 --> 00:00:59,120 when you add two text together for example you had James plus bond. 13 00:00:59,160 --> 00:01:01,320 It would give you James Bond. 14 00:01:01,320 --> 00:01:06,070 So we use it with a plus side is known concatenation. 15 00:01:06,360 --> 00:01:14,520 But when you add in numbers is known as addition subtraction is similar to addition in that it takes 16 00:01:14,520 --> 00:01:17,580 away one number from the other. 17 00:01:17,610 --> 00:01:25,230 So you doing some traction when you take in the way number figures and then you've got multiplication 18 00:01:26,190 --> 00:01:31,050 multiplication is when you multiply two numbers together. 19 00:01:31,500 --> 00:01:35,860 This symbol is an asterix makes is the definition. 20 00:01:35,880 --> 00:01:42,200 When you divide a number by another number this is the symbol a backslash. 21 00:01:42,680 --> 00:01:44,590 Max you've got a model source. 22 00:01:44,610 --> 00:01:52,400 This is also known as a remenda operator or modal operator. 23 00:01:52,500 --> 00:02:00,610 Basically what it does it only returns what is left when two numbers being divided together. 24 00:02:00,870 --> 00:02:03,980 It will only return what is left. 25 00:02:04,000 --> 00:02:06,270 It does not left to will return zero. 26 00:02:06,270 --> 00:02:14,980 So the only thing it does is it returns the remainder after the deviation has occurred. 27 00:02:15,720 --> 00:02:21,570 Please note there is an assignment operate on this sign here. 28 00:02:21,570 --> 00:02:25,860 This equates to refers to an assignment operator. 29 00:02:25,860 --> 00:02:33,870 It is a use to assign values or set a variable or something in terms of scrip. 30 00:02:34,020 --> 00:02:40,110 So any way you see the equals sign in Javascript is known as an assignment operator. 31 00:02:40,110 --> 00:02:44,260 It doesn't mean equals to so equals to endeavours script. 32 00:02:44,270 --> 00:02:45,530 Is this a different symbol. 33 00:02:45,540 --> 00:02:52,460 But where you see this one it means that some I say mean it is set in value or assigning value. 34 00:02:52,890 --> 00:02:57,160 Next we're going to talk about B comparison operators. 35 00:02:57,210 --> 00:03:02,880 These are operators using javascript when they want to compare values. 36 00:03:02,880 --> 00:03:09,000 So if you need to compare values in Javascript you use what we call a comparison operator. 37 00:03:09,120 --> 00:03:09,770 All right. 38 00:03:09,780 --> 00:03:12,810 This is my table of comparison. 39 00:03:13,120 --> 00:03:13,600 Up. 40 00:03:13,830 --> 00:03:21,270 So if you want to find out if something is equal to something in Javascript you use is a double equal 41 00:03:21,280 --> 00:03:21,870 sign. 42 00:03:21,990 --> 00:03:23,060 She is in this single. 43 00:03:23,070 --> 00:03:29,550 You are setting or assigning a value so to check if something was for something you use. 44 00:03:29,550 --> 00:03:31,930 Double equals to sign. 45 00:03:32,430 --> 00:03:35,830 And then if something is not equal it's equal to something. 46 00:03:35,850 --> 00:03:40,450 You use the symbol so you use this symbol here. 47 00:03:40,490 --> 00:03:49,590 If you need to find out if something is not equal to something for example if it's not equal to B is 48 00:03:49,590 --> 00:03:53,430 a symbol like that to find out next is it greater than. 49 00:03:53,460 --> 00:03:58,680 If you want to find the value is greater than another value. 50 00:03:58,680 --> 00:04:00,680 Next is the less than sign. 51 00:04:00,690 --> 00:04:06,790 This sign refers to a less down value values less than and then this is great and down not equal to. 52 00:04:06,990 --> 00:04:11,100 You need to if you want to find life values great and down or equal to. 53 00:04:11,110 --> 00:04:12,610 You use this symbol. 54 00:04:12,810 --> 00:04:18,480 If you find that the value is less than or equal to use this symbol. 55 00:04:18,480 --> 00:04:24,090 So these are the parries operators used in javascript. 56 00:04:24,390 --> 00:04:29,420 So in this video I went through some of the javascript operators. 57 00:04:29,520 --> 00:04:39,200 I covered the arithmetic operators and also mention the equals tool which is the assignment operator. 58 00:04:39,210 --> 00:04:47,070 I then went to talk about the comparison operators use when you need to compare values. 59 00:04:47,310 --> 00:04:48,950 Thank you so much for watching. 60 00:04:49,020 --> 00:04:52,040 I hope it has made sense if it hasn't. 61 00:04:52,050 --> 00:04:57,210 Please send me a message it be more than happy to explain further. 62 00:04:57,420 --> 00:04:58,290 Thank you. 63 00:04:58,290 --> 00:04:59,200 Bye for now.
