JavaScript - Break & Continue

Overview

Estimated time: 10–15 minutes

break exits a loop early; continue skips to the next iteration.

Learning Objectives

• Use break and continue to control loop flow.
• Avoid overuse that harms readability.

Prerequisites

• JavaScript - for...in & for...of

Examples

for (let i = 0; i < 5; i++) {
  if (i === 3) break;     // exit loop
  if (i % 2 === 0) continue; // skip even
  console.log(i); // 1
}

Common Pitfalls

• Nested loops with many breaks/continues can be hard to follow; refactor into functions when possible.
