for loop vs for each js

Comment

// Think of .forEach() like this:
// You're giving the loop a task (the callback function), and the loop keeps running through all items no matter what.
// You can stop that one task with return, but the loop has more tasks waiting — so it keeps going.


function example() {
  [1, 2, 3].forEach(
   // arrow function or callback function 
    (item) => {
    	if (item === 2) {
      		return; // ⛔️ Only exits the arrow function, not example()
    	}
   	}
  );

  console.log('This still runs!'); // ✅ Always runs
}



// With for...of, you're driving the loop yourself — so if you hit return,
// you’re telling the whole process: "We’re done here. Stop the car."

function example() {
  for (let item of [1, 2, 3]) {
    if (item === 2) {
      return; // ✅ Exits example() immediately
    }
  }

  console.log('This line won’t run if 2 is found');
}
