Assign value from successful promise resolve to external variable

Question

I have a pretty silly problem. Consider the following:

vm.feed = getFeed().then(function(data) {return data;});

getFeed() retu

Answer 1

You could provide your function with the object and its attribute. Next, do what you need to do inside the function. Finally, assign the value returned in the promise to the right place in your object. Here's an example:

let myFunction = function (vm, feed) {
    getFeed().then( data => {
        vm[feed] = data
    })
} 

myFunction(vm, "feed")

You can also write a self-invoking function if you want.
