### Throttle.sync
`Throttle.sync(tasks, options)`
Throttle.sync runs all the tasks synchronously.
Once again the tasks array is required, the [options](#options-object) are optional.
Throttle.sync runs all the tasks synchronously.
Once again the tasks array is required, the [options](#options-object) are optional.
Be aware that this method is simply a wrapper to pass `maxInProgress` with 1. So overwriting this option in the options object would run the tasks again in parallel.
### Throttle.raw
`Throttle.raw(tasks, options)`
The raw method instead of returning the tasks their results, will return a [result](#result-object--progress-callback) object.
Useful if you wan't more statistics about the execution of your tasks. Once again the tasks are required while the [options](#options-object) are optional.

| progressCallback | Function | Optional | callback with progress reports |
| nextCheck | Function | Optional | function which should return a promise, if the promise resolved true the next task is spawn, errors will propagate and should be handled in the calling code |
| ignoreIsFunctionCheck | Boolean | false | If one of the tasks is not a function an error is thrown, if this boolean is set to true we simply return the task itself |
#### Result object / Progress callback
The `progressCallback` and the `Raw` will return a `Result` object with the following properties:
|Property|Type|Start value|Definition|
|:---|:---|:---|:---|
|amountDone|Integer|0|amount of tasks which are finished|
|amountStarted|Integer|0|amount of tasks which started|
|amountResolved|Integer|0|amount of tasks which successfully resolved|
|amountRejected|Integer|0|amount of tasks which returned in an error and are aborted|
|amountNextCheckFalsey|Integer|0|amount of tasks which got a falsey value in the [nextCheck](#nextcheck)|
|rejectedIndexes|Array|[]|all the indexes in the tasks array where the promise rejected|
|resolvedIndexes|Array|[]|all the indexes in the tasks array where the promise resolved|
|nextCheckFalseyIndexes|Array|[]|all the indexes in the tasks array where the [nextCheck](#nextcheck) returned a falsey value|
|taskResults|Array|[]|array containing the result of every task|
| Property | Type | Start value | Definition |

#### nextCheck
All the `Throttle` methods have a `nextCheck` method which will be used to verify if a next task is allowed to start.
