📍 What is continue in JavaScript?

The continue statement is used to skip the current iteration of a loop and proceed with the next one. It's helpful when you want to ignore certain values or conditions without stopping the entire loop. 🔄

🧪 Syntax

continue;

That's it! A single statement that tells JavaScript to skip the rest of the loop body for the current iteration.

🔁 Using continue in a Loop

for (let i = 1; i <= 5; i++) {
  if (i % 2 === 0) {
    continue;
  }
  console.log(i);
}

Output: 1, 3, 5
The loop skips printing even numbers by using continue.

🔄 With while Loop

let i = 0;

while (i < 5) {
  i++;
  if (i === 3) {
    continue;
  }
  console.log(i);
}

Output: 1, 2, 4, 5
The number 3 is skipped.

📦 Real-World Use Case

You can use continue to skip invalid or unwanted items while processing an array:

const names = ["Alice", "", null, "Bob"];

for (let i = 0; i < names.length; i++) {
  if (!names[i]) {
    continue;
  }
  console.log("✅", names[i]);
}

Output:
✅ Alice
✅ Bob
