calcul elapsed time async function javascript

Question

I would like to calcul and display in a file the elapsed time for each call response.

Promise function

function callPromise(ms, promise) {
    return new Promise((resolve, reject) => {
        const timeoutId = setTimeout(() => {
            reject(new Error(`Timeout after ${ms} ms`))
        }, ms);
        promise.then(
            (res) => {
                clearTimeout(timeoutId);
                resolve(res);
            },
            (err) => {
                clearTimeout(timeoutId);
                reject(err);
            }
        );
    })
}

Response call

        const response = await callPromise(10, fetch(url, {
            method: request.method,
            headers: header,
            body: body
        }))

With console.time() ?

console.time("Elapsed time :");
const response = await callPromise(...);
console.timeEnd("Elapsed time :"); // Will log "Elapsed time : 6.9165ms"

And why didn't you say so in your question :/ You said "I would like to calcul and display" and that's what my answer does. – Jeremy Thille Oct 27 '21 at 08:57
