What is the correct way to wait for a response in a promise?
DD, help please how to perform such an action: there is a certain variable that at the moment of initialization has the value undefined, how to wait with the help of a promise when the value will be! = Undefined and after that execute the block instruction
Generally misunderstood. Promises are commonly used with asynchronous functions and their job is to get ANY response from them. And this answer can be either number / string / array / object, etc., or undefined, null, etc.
Observers are worth looking at for tracking variables.

I do not know any other options to monitor the variable (if you do not take into account the Timeout set, but it is).Anonymous
To place the code, please use CodePen or similar tool. Thanks you!
