为 WebAssembly 而设计
AssemblyScript 是专门针对 WebAssembly 的特性而设计的，让开发者能够对代码进行底层控制。
熟悉的 TypeScript 语法
它与 TypeScript 的相似性使得开发者无需学习新语言，即可轻松编译为 WebAssembly。
触手可及
与现有的 Web 生态系统集成 - 无需设置繁重的工具链。只需 npm install 即可！
#!runtime=stub
/** Calculates the n-th Fibonacci number. */
export function fib(n: i32): i32 {
var a = 0, b = 1
if (n > 0) {
while (--n) {
let t = a + b
a = b
b = t
}
return b
}
return a
}
#!html
<textarea id="output" style="height: 100%; width: 100%" readonly></textarea>
<script type="module">
const exports = await instantiate(await compile(), { /* imports */ })
const output = document.getElementById('output')
for (let i = 0; i <= 10; ++i) {
output.value += `fib(${i}) = ${exports.fib(i)}\n`
}
</script>

为什么选择 AssemblyScript？
“You are now able to write WebAssembly without learning a new language, and harness all these benefits WebAssembly might offer you. I think that is kind of powerful. AssemblyScript is absolutely usable, and very enjoyable!” – Surma, WebAssembly for Web Developers (Google I/O ’19)
“AssemblyScript is designed with WebAssembly and code size in mind. It's not an existing language that we are using for a new purpose but it's a language designed for WebAssembly. It has great wasm-opt integration, in fact it's built with it, and it's very easy to get good code size.” – Alon Zakai, Shipping Tiny WebAssembly Builds (WebAssembly Summit)
“I chose AssemblyScript because it has high-level readability and low-level control. It's like a high-level language but you get that low-level feeling and you can even directly write WebAssembly intrinsics if you want to.” – Peter Salomonsen, WebAssembly Music (WebAssembly Summit)
