Sequential code execution in angular/ typescript

Question

How can I make my code run sequentially? For example,

1. If I have a for loop which gets some data from a service, I want the n+1 iteration to run

Answer 1

I suggest adapting it to use the zip "combining operator" from rxjs:

EDIT: here is an example: https://www.learnrxjs.io/operators/combination/zip.html

Although in your case you would have to pass it as an array probably ( zipArray).
