So lets say you have this sync function you call a and another async function b that you want to put within a. And so you would have something like this:
async function b(){
//some code here
}
function a(){
}
And now lets say we add some code into a and call b:
async function b(){
//some code here
}
function a(){
b()
//other code here
}
Now lets say you want to run the code within a only if b has returned its promise. Well if you have direct access to b then its all fine, just make it a sync function. That would work but what if you didn't have access to b. Here comes the problem. If you specifically want to run it after b then you could use something like .then():
async function b(){
//some code here
}
function a(){
b().then(<results for example>=>{
//other code
})
}
But what if a was an async function, how would that work? Could i use await or anything of that sort?
You have to make a function async and await for b function, then b function will return data, otherwise it will return promise.
async function b(){
//some code here
}
async function a(){
const data = await b();
// Do something with data
}
