Async-Await or Promises with JavaScript functions [closed]
I am building an application in Cordova using Firebase for the database.
I have been using promises to get information back from the database and it works great, but once I get that back I usually have a series of functions that I need to call to update everything.
For example,
update local storage
call variable from local storage
reload page with updated storage information
I need to create/convert my JavaScript functions to be able to be called in succession.
javascript asynchronous promise async-await synchronous

Most likely your issues stem fromupdateCS()not returning a Promise (or even if it does, you're not using it)

I don't get your explanation why you "cant use a .then on this or place it in the .then above". Please try it and show us that code, the approach should work.

What you are really asking is how to implement a function after a promise is done. If so, then making the function an Async function will do the trick.
For information on async-await check out Async/await.

Yeah, basically I have 8 functions that get called through out my app. Some of them need to be called in succession for the other ones to work. For example: update local storage variable needs to be done updating before i call that local storage variable to populate what is on the page. then once this is all done reload the page. I read that async stuff but without a more specific example it has always been hard for me to reverse engineer.

@hefty_kat try watching youtube videos, I find them easier to understand. Check out this video: youtube.com/watch?v=IGoAdn-e5II. The concept is well explained in a simple manner.
