Modern Js의 제어 흐름에 관한 모든 것 (2)

Hoo-AH, 이 기사에서 우리는 js에서 Control-flow를 던지고 사용법을 배울 것입니다. 앞에서 언급했듯이 모든 코드는 예제와 결과가 포함된 하나의 Js 파일에 있습니다. 따라서 충분한 비디오를 읽는 데 5분이 걸립니다. 그것.

// for loops

for (let i = 0; i < 5; i++) // here we gonna print the numbers from 0 and stop at 4 because the condition is i is lessthan 5
{
    console.log(i); // output  0 1 2 3 4  

}

//looping throw data like array
const friends = ['Ahmed','hameed','hassan','ragab'];

for(let name = 0; name < friends.length; name++)
{
    console.log(friends[name]); // output 'Ahmed','hameed','hassan','ragab'
}

//======================================================================================

// while loop

let i = 0; //here we define the start point

while (i < 5) //here we define the condition
{
    console.log('in loop: ',i); // ouput is 
    i++; //here we iterating throw the the condition till it reach 4 

} 
let name = 0 ;
while (name < friends.length) 
{
    console.log(friends[name]); // output 'Ahmed','hameed','hassan','ragab'
    name++;
}

//======================================================================================


// do while loop  it's guarantee that the condition gonna excute one time at least even the condition isn't true!

let x = 5;
do {
    console.log('val of i: ',x); // output is val of i:  5
    x++
} while (x < 5);



let y = 0;
do {
    console.log('val of i: ',y); // output is 0 1 2 3 4 
    y++
} while (y < 5);

// if statements

const age = 25 ;

if (age > 20) {
    console.log('your are over 20 years'); // your are over 20 years

}

//======================================================================================

// if else & else if statement
const password = 'password';

if(password.length >= 12)
{
    console.log('that password mighty be strong');
}
else if (password.length >= 8 ) 
{
    console.log('password is long enougha');
}else{
    console.log(' password is not long enough');
