TypedArray.prototype.constructor is the hidden TypedArray constructor function, but each typed array subclass also defines its own constructor property. {{jsxref(\"TypedArray.prototype.length\")}} : Returns the number of elements held in the typed array. TypedArray.prototype[Symbol.toStringTag] : The initial value of the [TypedArray.prototype[Symbol.toStringTag]](/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol/toStringTag) property is a getter that returns the same string as the typed array constructor's name. It returns undefined if the this value is not one of the typed array subclasses. This property is used in {{jsxref(\"Object.prototype.toString()\")}}. However, because TypedArray also has its own toString() method, this property is not used unless you call Object.prototype.toString.call() with a typed array as thisArg.\n\nAll TypedArray subclasses also have the following instance properties\n\n{{jsxref(\"TypedArray.prototype.BYTES_PER_ELEMENT\")}} : Returns a number value of the element size for the different TypedArray objects.\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
