If the do work function was performing some operation, say, picking an item from queue and performing some operation. How would I get the execution times for doWork
function over time. I want to find out how much time doWork
takes to complete at an average.
Sample Code
function doWork () {
return Promise.resolve({first: 'Tony', last: 'Starks'})
}
async function wrapper () {
console.time('wrapper')
const response = await doWork()
console.timeEnd('wrapper')
return response
}
Promise.all([
wrapper(),
wrapper(),
wrapper()
]).then((result) => console.info(result))
Output
wrapper: 0.388ms
[ { first: 'Tony', last: 'Starks' },
{ first: 'Tony', last: 'Starks' },
{ first: 'Tony', last: 'Starks' } ]
