WebAssembly.Memory.prototype.buffer
The buffer
prototype property of the WebAssembly.Memory
object returns the buffer contained in the memory.
Examples
Using buffer
The following example (see memory.html on GitHub, and view it live also) fetches and instantiates the loaded memory.wasm byte code using the WebAssembly.instantiateStreaming()
method, while importing the memory created in the line above. It then stores some values in that memory, then exports a function and uses it to sum some values.
WebAssembly.instantiateStreaming(fetch('memory.wasm'), { js: { mem: memory } })
.then(obj => {
var i32 = new Uint32Array(memory.buffer);
for (var i = 0; i < 10; i++) {
i32[i] = i;
}
var sum = obj.instance.exports.accumulate(0, 10);
console.log(sum);
});
