The cleaner way would be to not use .forEach. It’s almost never needed if you’re using TypeScript or a modern version of JavaScript:
example() {
for (let item of this.items) {
if (item === 3) {
return;
}
}
// Do stuff in case forEach has not returned
}
If the code inside your loop doesn’t have any side-effects and you’re just checking for a condition on each item, you could also use a functional approach with .some:
example() {
if (this.items.some(item => item === 3)) {
return;
}
// Do stuff in case we have not returned
}
