[−][src]Struct rslint_core::groups::errors::NoAsyncPromiseExecutor
Disallow async functions as promise executors.
Promise executors are special functions inside new Promise()
constructors which take a resolve
and
reject
parameter to resolve or reject the promise. The function is a normal function therefore it could be
an async function. However this is usually wrong because:
- Any errors thrown by the function are lost.
- It usually means the new promise is unnecessary.
Incorrect code examples
let foo = new Promise(async (resolve, reject) => {
doSomething(bar, (err, res)) => {
/* */
});
});
let foo = new Promise(async function(resolve, reject) => {
/* */
});
Correct code examples
Use a normal non-async function.
let foo = new Promise(function(resolve, reject) => {
/* */
})
