Array (Built-in Object)
Arrays store ordered lists of data. Data is stored at indices enumerated beginning with zero,
which are accessed using the array access ([]) operator. Allocation of array memory is handled
by the interpreter, so there is no need to explicitly resize arrays to accommodate more data. In
addition, arrays are permitted to be sparse, that is, to have ―holes‖ consisting of an arbitrary
number of unused indices. Any index that has not been assigned data has value undefined,
and the highest index addressable is 232 –1 because indices are converted to unsigned 32-bit
integers before use. JavaScript arrays are one-dimensional, but since array elements can be of
any type, multidimensional arrays are supported as arrays with elements that are arrays.
You can explicitly remove a value from an array using the delete operator, but there is no way
to destroy an array other than by setting the variable that holds its reference to null.
Constructor
