00:00:02

video we will look at the

00:00:03

operator was java-script I started

00:00:07

let's move on to fike script. Jess and

00:00:10

consider the if statement, write

00:00:15

the variable x with the value 25 and the

00:00:21

if condition in parentheses of which we indicate the conditions

00:00:26

[music]

00:00:28

let's say x is greater than ten

00:00:32

and if the result is ru based on the results of

00:00:38

fulfilling this condition, then the

00:00:41

block of code is executed and let's

00:00:46

display the slave in the console, save it and let's

00:00:54

see what will be displayed in

00:00:55

the browser

00:00:57

as we see, since our conditions are correct and

00:01:01

we have received the values of slave, if

00:01:08

we want to execute more than one

00:01:10

instruction, then we need to include a block of code in

00:01:13

curly braces, let's do this, we

00:01:20

create curly braces and

00:01:23

write

00:01:26

[music]

00:01:34

we save two instructions and launch our browser and we

00:01:39

already get two values

00:01:42

[music] it

00:01:46

is recommended to always use

00:01:48

curly braces even if

00:01:51

only one command is executed,

00:01:53

this improves the readability of the code next

00:02:01

let's look at a block such as

00:02:06

alles the if statement may contain an

00:02:09

optional lc block in other

00:02:13

words

00:02:14

otherwise it is executed when the condition is false

00:02:18

for example

00:02:20

[music]

00:02:26

[music]

00:03:01

then we will write our if statement and

00:03:05

set the conditions

00:03:08

[music]

00:03:26

then we will display an alert and write

00:03:35

yes you are an expert

00:03:46

then we will write our blog lc that is, how do

00:03:50

we remember if a condition is a given condition for

00:03:55

us it doesn’t match, it

00:03:58

will automatically jump to lc,

00:04:01

then we will write an alert inside of which

00:04:07

we will set but this is not correct

00:04:16

[music]

00:04:23

save, restart the page, set the

00:04:31

current year and as we see we get

00:04:36

an alert with the value

00:04:38

yes, you are an expert if we have

00:04:44

several conditions then we use lc iv

00:04:51

sometimes you need to check several

00:04:54

variants of conditions for this we will now

00:04:57

look at became so if

00:05:04

[music]

00:05:34

[music]

00:05:41

[music]

00:06:06

we will set the first condition if it is

00:06:13

true we will display an alert with the

00:06:20

value too small

00:06:28

[music]

00:06:31

Next we will set all so if the condition of

00:06:38

which will be

00:06:42

[music]

00:06:53

more than 24

00:06:56

[music]

00:07:02

[music]

00:07:11

with the value

00:07:13

too much Next we will specify the elso

00:07:21

alert block Save it correctly and

00:07:42

let's see what will be displayed in our

00:07:45

browser Let's say 21 Too little

00:07:52

Restart our page

00:07:56

Let's say 26 too much and launch

00:08:03

our page

00:08:05

correctly, then let's write the next

00:08:10

entry,

00:08:14

we'll comment out what we've discussed, and we'll uncomment this

00:08:21

[music]

00:08:27

save and write it all using the

00:08:32

ternary operator, set the

00:08:40

resort variable, which will all contain

00:08:51

conditions? ? for us it means

00:09:01

the instruction if then for us:

00:09:10

which means elso and we

00:09:17

can hit everything unnecessary, save it and let's

00:09:23

go to the browser to visually

00:09:26

examine this example,

00:09:29

write down 2020 incorrectly, then let's

00:09:36

write down the current year and get a

00:09:41

positive answer

00:09:43

[music]

00:09:44

on this I have everyone subscribe to my

00:09:47

channel like and see you in the next

00:09:49
