How to use the Javascript Optional Chaining operator (?.)

Great read man! Weldone.

Well done. A good read bro!

Nice article! Really like this approach 🤩

Welcome to Hashnode, I've been using optional chaining at my work place without knowing what's it called 😲, I should have asked questions...

Nicely written and explained!

Thanks for this tip, nice article👏

Nice article. 👍

This would still throw cannot read property color of undefined if yourObjectName does not exist:

if (yourObjectName.color && yourObjectName.color === 'blue') {
  return 'Blue is cool';
}

Perhaps you meant:

if (yourObjectName && yourObjectName.color === 'blue') {
  return 'Blue is cool';
}
