Convert Promise Chains To Async Await Automatically Youtube From promise syntax to async await using the fetch api as an example. this can apply to other use cases, not just fetch api. We have to be careful and understand how async await works. the converted code doesn't behave exactly the same in the twitter example. before conversion the function returns a promise that resolves with undefined, and console.log(err) is called. after conversion, the function returns a promise that rejects, and console.log(err) is not called. Visual studio code provides a nice feature that allows developers to convert chains of promise.then() calls to async await calls automatically. this work with both typescript and javascript. you can use it as follows: first, select the code that conatins the promise.then() calls, next, click the lightbulb icon which will appear, finally, choose. First things first: async await is not a total replacement for promises. async await is built on top of promises, and it allows us to write asynchronous code more comfortably. it is just a new way of writing asynchronous code, besides promises and callbacks. it makes it look more “synchronous” too. now, let’s see the same code re written.
