[JavaScript] Loops and iterations

Loops

Using a loop simply means : Repeat this code until some condition is true

🔮 while loop

while (condition) {
  // code to be executed while the condition is true
}

The while loop in JS

• the condition : once the condition is false, the loop will end;
• the code to execute : the purpose of the loop is to run some code a certain number of times.

let counter = 1;

while (counter <= 10){
  console.log(counter);
  counter += 1;
} 

While loop in grpah

🔮 for loop

• A forloop is much like the whileloop, except that some of the functionalities you had to do on your ownn are included in it.
• for loop : i will be started from 1 and incremented 1 until the 10.

for (let i = 1; i <= 10; i++)
{
    console.log(i);
}

🔮 Nested loops

//  Creating the loop...
for (let i = 1; i <= 50; i++) {
  //  when at least one condition is true, run the code
  if (i % 10 === 0 || i % 15 === 0) {
    console.log('Donkey!');
  }

  // when both conditions are true, run the code
  if (i % 2 !== 0 && (i - 1) % 10 !== 0) {
    console.log('Monkey!');
  }

  //  on numbers divisible by 5, continue to the next iteration
  if (i % 5 === 0) {
    continue;
  }

  //  ... and console.log the variable i
  console.log(i);
}
