#### Array Properties #### Array Properties
There are two properties that control the "size" of an array: There are two properties that control the "size" of an array:
* `len`: *length* - the number of defined elements of the array * `len`: *length* - the number of pre-allocated and initialized elements in the array
* `cap`: *capacity* - the number of elements for which memory space has been reserved. The array can * `cap`: *capacity* - the amount of memory space which has been reserved for elements,
grow up to this size without being reallocated. Usually, V takes care of but not initialized or counted as elements. The array can grow up to this size without
this property automatically but there are cases where the user may want to do manual being reallocated. Usually, V takes care of this property automatically but there are
optimizations (see [below](#array-initialization)). cases where the user may want to do manual optimizations (see [below](#array-initialization)).
