API

pTimes(count, mapper, options?)

Returns a Promise that is fulfilled when all promises returned from mapper are fulfilled, or rejects if any of the promises reject. The fulfilled value is an Array of the fulfilled values returned from mapper in order.

count

Type: number

Number of times to call mapper.

mapper(index)

Type: Function

Expected to return a Promise or value.

options

Type: object

concurrency

Type: number
Default: Infinity
Minimum: 1

Number of concurrently pending promises returned by mapper.

stopOnError

Type: boolean
Default: true

When set to false, instead of stopping when a promise rejects, it will wait for all the promises to settle and then reject with an aggregated error containing all the errors from the rejected promises.
