Good news – the new ES2020 features are now finalized! This means we now have a complete idea of the changes happening in ES2020, the new and improved specification of JavaScript.

In this video, we're going to explore, in my opinion, the most important feature of ES2020 which is Optional Chaining.

Optional chaining syntax allows you to access deeply nested object properties without worrying if the property exists or not. If it exists, great! If not, undefined will be returned. Super convenient!
