arrayLike

Can be read as if it were an array.

Description

An "array-like" object in Javascript, is one which can be read like an array (using .length and [] indexing), but is not actually an array - i.e. it might not have methods such as .push(), .pop() etc. Array-like objects can be useful to provide a simple and common interface for an object that can hold multiple values. A well known example of this type of object is jQuery.

Use in DataTables

Many of the DataTable.Dom methods, including its DataTable.Dom.s() selector can make use of array-like objects, allowing seamless interoperability with libraries such as jQuery.
