Loop Control: break, continue

1. break

Terminates the loop entirely.

Example:

JavaScript
for (let i = 0; i < 5; i++) {
  if (i === 3) break;
  console.log(i);  // Prints 0, 1, 2
}

Example with break:

Let’s say you have a list of numbers and you’re looking for the first number greater than 5.

JavaScript
let numbers = [1, 2, 3, 6, 8, 9];

for (let i = 0; i < numbers.length; i++) {
    if (numbers[i] > 5) {
        console.log("Found a number greater than 5:", numbers[i]);
        break;  // Stop the loop when the first number greater than 5 is found
    }
}

Output:
Found a number greater than 5: 6

2. continue

Skips the current iteration and proceeds to the next one.

Example:

JavaScript
for (let i = 0; i < 5; i++) {
  if (i === 3) continue;
  console.log(i);  // Prints 0, 1, 2, 4
}

Example with continue:

Now, let’s say you want to print only the numbers greater than 5, skipping all others.

JavaScript
let numbers = [1, 2, 3, 6, 8, 9];

for (let i = 0; i < numbers.length; i++) {
    if (numbers[i] <= 5) {
        continue;  // Skip the current iteration if the number is less than or equal to 5
    }
    console.log(numbers[i]);
}

Code Output:
6
8
9
