await operator should be used at async function call when the resolved value is needed

• MISSING_AWAIT
• Error

This rule applies when the await operator appears to be missing at an async function call.

The return value of an async function is always a Promise object, and the resolved value can be obtained by using await operator.

If the return value of an async function is used in a context inappropriate for a Promise object, it is likely that the resolved value is intended, but the await operator is mistakenly omitted.

Noncompliant Code Example

async function fetch(url) {
    return doFetch(url);
}
async function getInfo() {
    const result = fetch('/info'); // MISSING_AWAIT alarm
    if (result.status === 200) {
        return result.text();
    }
    throw new Error('Bad response');
}

Compliant Code Example

async function fetch(url) {
    return doFetch(url);
}
async function getInfo() {
    const result = await fetch('/info');
    if (result.status === 200) {
        return result.text();
    }
    throw new Error('Bad response');
}
