This method is available on both pool implementations and returns a promise with the task function execution response.
+### `pool.mapExecute(data, name, transferList)`
+
+`data` Iterable objects that you want to pass to your worker task function implementation.
+`name` (optional) A string with the task function name that you want to execute on the worker. Default: `'default'`
+`transferList` (optional) An array of transferable objects that you want to transfer to your [`ThreadWorker`](#class-yourworker-extends-threadworkerclusterworker) worker implementation.
+
+This method is available on both pool implementations and returns a promise with the task function execution responses array.

### `pool.start()`
This method is available on both pool implementations and will start the minimum number of workers.
- `WorkerChoiceStrategies.ROUND_ROBIN`: Submit tasks to worker in a round robin fashion
- `WorkerChoiceStrategies.LEAST_USED`: Submit tasks to the worker with the minimum number of executing and queued tasks
- - `WorkerChoiceStrategies.LEAST_BUSY`: Submit tasks to the worker with the minimum tasks total execution and wait time
+ - `WorkerChoiceStrategies.LEAST_BUSY`: Submit tasks to the worker with the minimum tasks execution time
- `WorkerChoiceStrategies.LEAST_ELU`: Submit tasks to the worker with the minimum event loop utilization (ELU)
- `WorkerChoiceStrategies.WEIGHTED_ROUND_ROBIN`: Submit tasks to worker by using a [weighted round robin scheduling algorithm](./worker-choice-strategies.md#weighted-round-robin) based on tasks execution time
- `WorkerChoiceStrategies.INTERLEAVED_WEIGHTED_ROUND_ROBIN`: Submit tasks to worker by using an [interleaved weighted round robin scheduling algorithm](./worker-choice-strategies.md#interleaved-weighted-round-robin-experimental) based on tasks execution time (experimental)
- `tasksStealingOnBackPressure` (optional) - Tasks stealing enablement under back pressure.
- `tasksFinishedTimeout` (optional) - Queued tasks finished timeout in milliseconds at worker termination.
- Default: `{ size: (pool maximum size)^2, concurrency: 1, taskStealing: true, tasksStealingOnBackPressure: true, tasksFinishedTimeout: 2000 }`
+ Default: `{ size: (pool maximum size)^2, concurrency: 1, taskStealing: true, tasksStealingOnBackPressure: false, tasksFinishedTimeout: 2000 }`
- `workerOptions` (optional) - An object with the worker options to pass to worker. See [worker_threads](https://nodejs.org/api/worker_threads.html#worker_threads_new_worker_filename_options) for more details.
`opts` (optional) An object with these properties:
- `killBehavior` (optional) - Dictates if your worker will be deleted in case a task is active on it.
- **KillBehaviors.SOFT**: If `currentTime - lastActiveTime` is greater than `maxInactiveTime` but a task is still executing or queued, then the worker **won't** be deleted.
- **KillBehaviors.HARD**: If `currentTime - lastActiveTime` is greater than `maxInactiveTime` but a task is still executing or queued, then the worker will be deleted.
+ **KillBehaviors.SOFT**: If `currentTime - lastActiveTime` is greater than `maxInactiveTime` but the worker is stealing tasks or a task is executing or queued, then the worker **won't** be deleted.
+ **KillBehaviors.HARD**: If `currentTime - lastActiveTime` is greater than `maxInactiveTime` but the worker is stealing tasks or a task is executing or queued, then the worker will be deleted.
This option only apply to the newly created workers.
Default: `KillBehaviors.SOFT`
