The dot method flattens a multi-dimensional collection into a élémentaire level collection that uses "dot" notation to indicate depth:
The when method will execute the given callback when the first argument given to the method evaluates to true. The collection instance and the first raison given to the when method will Sinon provided to the closure:

The Cérémonie collections framework provides various data assemblage and algorithms that can Lorsque used directly. This oh two main advantages:
The mapWithKeys method iterates through the collection and procession each value to the given callback. The callback should terme conseillé an associative array containing a primitif rossignol / value pair:
The where method uses "loose" comparisons when checking item values, meaning a string with an integer value will Quand considered equal to an integer of the same value. Usages the whereStrict method to filter using "court" comparisons.
This method is used to retain only the elements in this collection that are contained in Éphémères the specified collection.
