Fix the “‘await’ has no effect on the type of this expression” warning in React. To fix the “‘await’ has no effect on the type of this expression” warning in React, we should make sure that we only use await on expressions that returns a promise.
javascript – ‘await’ has no effect on the type of this expression – Stack Overflow
In my code I have an array of user names. I’m trying to go through each name, check whether the user exist in the database and create the user. The problem is, my linter is saying ‘await’ has no effect on the type of this expression in the places I have marked:

K-pop slang: terms you should know, part 1 – Haneul Ssem Basically Visual Studio Code gives me the note ‘await’ has no effect on the type of this expression. but I am note able to track the actual problem down. Of course my example here is a bit nested and therefor a bit more complex than it maybe has to be. It all starts with an array where I want to check it a value is valid.

Await’ Has No Effect On The Type Of This Expression
In this example, the await in doTheAsyncAwait fn waits for the Promise inside doSomething to resolve (waits for 3 seconds). Even though it’s returning void, clearly the await has an effect on it.. Not sure if I should file this as a separate issue since this isn’t in particular about setState.But I ran into this warning when I was making a form and I’m letting the parent component in React “await” has no effect in this type expression. DanCouper: const result = await users.map(async (user) => ( name: user, followers: await getFollowers(user) )); It just returns everything with a promise. DanCouper November 18, 2019, 8:40am 4. Ah wasn’t tested, just written on phone, need to resolve the map of promises so should be more like

Best sustainable Breakfast Spots in Eco-Hotels worldwide Jun 29, 2023When an await is encountered in code (either in an async function or in a module), the awaited expression is executed, while all code that depends on the expression’s value is paused and pushed into the microtask queue.The main thread is then freed for the next task in the event loop. This happens even if the awaited value is an already-resolved promise or not a promise.

Night. Sleep. Death. The Stars. by Joyce Carol Oates | Goodreads Aug 21, 2023🙁 Actual behavior. The type of execute is inferred as => void, so TypeScript displays a spurious warning on the await execute(); line, “‘await’ has no effect on the type of this expression.(80007)”.. 🙂 Expected behavior. TypeScript infers the type as => void | => Promise<void>, and calling await execute() generates no warnings.. Based on the FAQ, I would expect explicitly assigning

Rule proposal: `no-nested-await` · Issue #1458 · sindresorhus/eslint-plugin-unicorn · GitHub The await expression causes async function execution to pause, to wait for the Promise ‘s resolution, and to resume the async function execution when the value is resolved. It then returns the resolved value. If the value is not a Promise, it’s converted to a resolved Promise. If the Promise is rejected, the await expression throws the rejected
