Can you clarify what is unclear after reading e.g. this document? tc39.github.io/process-document – Sofer

"Which stage code is recommended for writing production code" - It's your code. Use whichever stage you feel comfortable using. – Usherette

@JoeClay I know this is my code and I can add whatever I want to add. If you see my question I have clearly mentioned which one is recommended from experts like you for writing production ready code. – Shelter

Answer 1

To be honest, it is really depends on yourself.

As you can see, you can only be sure that a feature will be included in the standard once its proposal has reached stage 4. Then its inclusion in the next ECMAScript release is probable, but not 100% sure, either (it may take longer).

Object.observe is an example of an ECMAScript proposal that had progressed until stage 2, but was ultimately withdrawn.
