Severity: Error

Category: Best Practices

Description

An async Promise executor won’t surface exceptions if it fails. If you are already awaiting results in the executor, the Promise itself might not be required; please review your implementation.

Non-Compliant Code Examples

new Promise(async function foo(resolve, reject) {})
new Promise(async (resolve, reject) => {})

Compliant Code Examples

new Promise((resolve, reject) => {})
new Promise((resolve, reject) => {}, async function unrelated() {})
new Foo(async (resolve, reject) => {})
