1 00:00:00,540 --> 00:00:03,590 Hello and welcome to this video. 2 00:00:03,630 --> 00:00:15,360 In this video we introduce you to the javascript string operators string operators are used to add strings 3 00:00:15,750 --> 00:00:28,560 together using the addition operator when the addition operator is used with strings. 4 00:00:28,560 --> 00:00:35,180 It is referred to as concatenation operator. 5 00:00:35,730 --> 00:00:45,060 So when you're using string operators you can use the addition operator or you can also use the addition 6 00:00:45,330 --> 00:00:52,620 and assignment operator which is the plus equals two which is the assignment so you can use both types 7 00:00:52,620 --> 00:01:00,650 of operators to achieve a string operator function. 8 00:01:00,660 --> 00:01:05,610 So let me quickly illustrate with a couple of basic examples. 9 00:01:05,880 --> 00:01:15,380 So I have got my console here and I am going to create some variables or to create a variable just type 10 00:01:15,380 --> 00:01:18,340 in the R and give the variable any name. 11 00:01:18,360 --> 00:01:27,120 I'm going to give this variable a name one and I'm going to give it a value of. 12 00:01:27,360 --> 00:01:28,560 Show me 13 00:01:32,850 --> 00:01:33,690 that is a value. 14 00:01:35,640 --> 00:01:43,320 And I'm going to create another variable and I'm going to call this variable number to go and assign 15 00:01:43,320 --> 00:01:51,960 this value of the money. 16 00:01:51,960 --> 00:01:55,770 So that's my value for variable number two. 17 00:01:55,770 --> 00:02:07,200 I'm going to create another variable variable number three and I'm going to make this variable value 18 00:02:07,230 --> 00:02:16,890 of variable one plus I'm now using the string operators or contact the value to my adding variable one 19 00:02:17,790 --> 00:02:25,950 and I'm using blank quotes here the blank quotes here basically will create a space between the two 20 00:02:25,950 --> 00:02:27,070 variables. 21 00:02:27,480 --> 00:02:34,600 And I use another concatenation to add the variable number two. 22 00:02:35,250 --> 00:02:41,550 So now variable number three will equal to the value of variable number 1 and 2. 23 00:02:41,550 --> 00:02:47,940 So now if I call variable number three it would give me the value. 24 00:02:47,940 --> 00:02:50,200 Show me the money. 25 00:02:50,280 --> 00:02:57,780 So that's one way of using that string operator using the addition Operator will you use it this way 26 00:02:57,790 --> 00:03:00,660 is called concatenation. 27 00:03:00,660 --> 00:03:05,290 So let me show you a second way where you can use the assignment operator. 28 00:03:05,670 --> 00:03:13,370 So I'm going to create a very poor code C and I'm gonna give it a value call. 29 00:03:15,030 --> 00:03:15,750 Hello. 30 00:03:18,360 --> 00:03:21,040 OK. 31 00:03:21,420 --> 00:03:25,370 That would be the value of that variable. 32 00:03:25,410 --> 00:03:32,310 Now I'm going to use the assignment operator to add to the value of that variable and the way I will 33 00:03:32,310 --> 00:03:32,820 do this. 34 00:03:32,830 --> 00:03:39,120 I'll just call the variable by name which is C and I use the assignment operator. 35 00:03:39,450 --> 00:03:49,230 So I'm using the addition equals two together and I'm going to add a value add to a space to create 36 00:03:49,230 --> 00:03:53,980 some space between the text say world. 37 00:03:56,100 --> 00:04:07,730 And you can see now it has now added the word world two helos who are now concatenate it or use added 38 00:04:07,730 --> 00:04:09,320 two strings together. 39 00:04:09,330 --> 00:04:17,040 So I've used the assignment operator to achieve that and I've also used the addition operator in this 40 00:04:17,040 --> 00:04:18,710 case to achieve that. 41 00:04:18,720 --> 00:04:23,690 So that's basically how you use string operators. 42 00:04:24,330 --> 00:04:25,620 Thank you for watching. 43 00:04:25,800 --> 00:04:26,640 Bye for now.
