await, it can be easy to forget to
await a promise which can result in async tasks running in an unexpected order. Thus, we require that every promise in an
async function is consumed in some way, so that there's a well-defined order in which async tasks are resolved. To fix this check, you can do one of the following:
asyncfrom the function, and instead use normal promise chaining.
As a last resort, if you really want to use
async and can't
await the promise, you can just assign it to a variable, like so
let ignoredPromise = returnsPromise();
This makes your intent to ignore the result of the promise explicit, although it may cause “declared but never used” warning with some linters.
