Optional Chaining Operator (?.) in JavaScript

The optional chaining operator in JavaScript is convenient as it allows the developer to specify an object's property as being optional, and only return a value if the specified property is not "null" or "undefined" - otherwise return "undefined".
It's helpful when accessing data from an API, or generally where you're not too sure what data will look like, or knowing where optional fields exist. It can also be used in combination with the nullish coalescing operator to provide smart defaults 🙂

I opened multiple tabs to learn about optional changing operators, but after watching your video, I didn't need to look for others.

[@fahmidhossainSakib]

thanks for comparing the optional operator with the ternary operator of java at 2:46 . It made me understand profoundly.

There are a billion different names for this operator

Why do you keep calling Question mark(?) a dollar sign($)? 😩😄

[@softwarejobkosam7327]

Super bro..from india...my suggestion.. please speak in slow for clear understanding of your English.. Do complete javascript tutorial

[@bullettime2808]

My suggestion: learn English

[@softwarejobkosam7327]

@@bullettime2808 as a youtube r ...take suggestion s positively.....it's good for your channel improvement.. 👍

[@smoothbeak]

I feel as though he already speaks quite slowly (and clearly too)

[@billsmoke3929]

Not to be rude but he is speaking clearly and slowly

[@damianodamian7907]

His way of explaining is crystal clear I would say. I personally find difficult to understand English spoken by Indians. Probably is the same the way around. Use subtitles, it will help you
