Arrays
An array holds a series of data elements of the type (numeric, boolean, string). Individual elements are accessed by their position in the array using an index parameter enclosed in square brackets [ i ]. Array indexes consist of a consecutive range of integers (starting at 0 through the maximum index value). Some arrays are multi-dimensional, meaning they are indexed by separate values (delimited by commas) for each dimension such as [ i, j ]. Generally, one- and two-dimensional arrays are the most common.
