The elements of a typed array are all numbers. The constructor used to create the typed array determines the type (signed or unsigned integers or floating point) and size (in bits) of the numbers.
Typed arrays have a fixed length.
The elements of a typed array are always initialized to 0 when the array is created.
There are eight kinds of typed arrays, each with a different element type. You can create them with the following constructors:
|signed 16-bit short integers|
|unsigned 16-bit short integers|
|signed 32-bit integers|
|unsigned 32-bit integers|
|32-bit floating-point value|
