TypedArray.prototype.buffer
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since juillet 2015.
La propriété buffer est un accesseur représentant l'ArrayBuffer représenté par le TypedArray lors de la construction de l'objet.
Exemple interactif
// Create an ArrayBuffer with a size in bytes
const buffer = new ArrayBuffer(8);
const uint16 = new Uint16Array(buffer);
console.log(uint16.buffer.byteLength);
// Expected output: 8
Syntaxe
js
typedArray.buffer;
Description
La propriété buffer est un accesseur dont le mutateur correspondant vaut undefined. Cela signifie que cette propriété n'est accessible qu'en lecture seule. La valeur de la propriété est déterminée lors de la construction du TypedArray et ne peut pas être modifiée. TypedArray est un des objets TypedArray.
Exemples
js
var buffer = new ArrayBuffer(8);
var uint16 = new Uint16Array(buffer);
uint16.buffer; // ArrayBuffer { byteLength: 8 }
