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) {}
}
