This very simple example shows usage of WebAssembly.
|
||||
|
||||
WebAssembly modules can be imported like other modules. Their download and compilation happens in parallel to the download and evaluation of the javascript chunk.
|
||||
|
||||
# example.js
|
||||
|
||||
``` javascript
|
||||
import("./add.wasm").then(addModule => {
|
||||
console.log(addModule.add(22, 2200));
|
||||
import("./math").then(math => {
|
||||
console.log(math.add(10, 101));
|
||||
console.log(math.factorial(15));
|
||||
console.log(math.factorialJavascript(15));
|
||||
console.log(math.fibonacci(15));
|
||||
console.log(math.fibonacciJavascript(15));
|
||||
timed("wasm factorial", () => math.factorial(1500));
|
||||
timed("js factorial", () => math.factorialJavascript(1500));
|
||||
timed("wasm fibonacci", () => math.fibonacci(22));
|
||||
timed("js fibonacci", () => math.fibonacciJavascript(22));
|
||||
});
|
||||
});
|
||||
|
||||
function timed(name, fn) {
|
||||
if(!console.time || !console.timeEnd)
|
||||
return fn();
|
||||
// warmup
|
||||
for(var i = 0; i < 10; i++)
|
||||
fn();
|
||||
console.time(name)
|
||||
for(var i = 0; i < 5000; i++)
|
||||
fn();
|
||||
console.timeEnd(name)
|
||||
}
|
||||
```
|
||||
|
||||
# math.js
|
||||
|
||||
``` javascript
|
||||
import { add } from "./add.wasm";
|
||||
import { factorial } from "./factorial.wasm";
|
||||
import { fibonacci } from "./fibonacci.wasm";
|
||||
|
||||
export { add, factorial, fibonacci };
|
||||
|
||||
export function factorialJavascript(i) {
|
||||
if(i < 1) return 1;
|
||||
return i * factorialJavascript(i - 1);
|
||||
}
|
||||
|
||||
export function fibonacciJavascript(i) {
|
||||
if(i < 2) return 1;
|
||||
return fibonacciJavascript(i - 1) + fibonacciJavascript(i - 2);
|
||||
}
