Hoo-AH , In this article we will go throw Control-flow in js and learn how to use , As i mentioned before in ES6 vars&dataTypes all codes will be in one Js file with examples and results, So,enough videos just take 5 mins to read it.
File will contain topics like:
- For loops
- Looping throw data like arrays
- Wile loop
- Do While loop
- If statements
- If else & else if statement

// 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');
}
