async function & no return await All In One
async function & no return await All In One
async function
return await
错误的使用方式 ❌
ESLint no-return-await
/*eslint no-return-await: "error"*/
async function foo() {
// ESLint 检查 ✅
return bar();
}
async function foo() {
// 绕过 ESLint 检查 ❌
await bar();
return;
}
// This is essentially the same as `return await bar();`, but the rule checks only `await` in `return` statements
async function foo() {
// 绕过 ESLint 检查 💩
const x = await bar();
return x;
}
// In this example the `await` is necessary to be able to catch errors thrown from `bar()`
async function foo() {
try {
// 只有需要使用 try...catch 捕捉错误的时候,才需要使用 return await 来获取错误信息 ✅
return await bar();
} catch (error) {}
}
