In my code, there is an async function that calls another async function:
const func1 = async () => {...}
const func2 = async () => {func1()}
I am curious whether it is necessary or redundant to use await when calling func1() inside func2 ?
const func2 = async () => {await func1()}
It is generally recommended to use the await keyword when calling a nested function.
If you do not use await with func1, it will run in a "fire and forget" mode, making it difficult to determine if it was successful or not. Additionally, code lines after func1 in func2 may execute before func1 is finished.
The only scenario where it might be appropriate not to use await is when you want to return a promise from your function.
Example:
const func2 = async () => { return func1(); }
await func2();
By returning the promise, it will be seamlessly awaited when calling func2 using await.
