+Internally, the V8 engine can represent `Array`s following one of two approaches:
 
 - **Fast Elements**: linear storage for compact keys sets.
-- **Dictionary Elements**: hash table storage otherwise (more expensive to access on runtime).

-If you want that V8 represents your `Array` in the `Fast Elements` form, you need to have a special considerations:
+If you want V8 to represent your `Array` in the `Fast Elements` form, you need to take into account the following:
 
 - Use contiguous keys starting at `0`.
 - Don't pre-allocate large `Array` (e.g. *> 64K* elements) that you don't use.
-- Don't delete elements, in special in numeric `Array`'s.
+- Don't delete elements, specially in numeric `Array`'s.
 - Don't load uninitialized or deleted elements.

+Another consideration: any name used as property name that is not a string is stringified via `.toString()`, so:
 
 - `1` will be `'1'`.
 - `undefined` will be `'undefined'`.
