Description

TypedArray objects differ from each other in the number of bytes per element and in the way the bytes are interpreted. The name property describes what data type the array consists of. It has three parts:

  • The first part can be Int for integer, Uint for unsigned integer, or Float for floating point.
  • The second part is a number describing the bit size of each element. Since 64-bit integers are too large to be represented without loss of precision with JavaScript numbers, the elements are stored as BigInt values instead, and the first part is prefixed with "Big", becoming either BigInt or BigUint.
  • Finally, the name terminates with Array or ClampedArray. Uint8ClampedArray has details about clamped arrays.

Examples

Using name

Int8Array.name;         // "Int8Array"
Uint8Array.name;        // "Uint8Array"
Uint8ClampedArray.name; // "Uint8ClampedArray"
Int16Array.name;        // "Int16Array"
Uint16Array.name;       // "Uint16Array"
Int32Array.name;        // "Int32Array"
Uint32Array.name;       // "Uint32Array"
Float32Array.name;      // "Float32Array"
Float64Array.name;      // "Float64Array"
BigInt64Array.name;     // "BigInt64Array"
