AssemblyScript SDK

[localvar]

As the WebAssembly filter is almost done, users will be able to leverage WebAssembly to extend the ability of Easegress soon.

Easegress has provided a set of host functions for the interoperation between Easegress and user-developed WebAssembly code, and because it is really painful to write WebAssembly code directly, Easegress also needs to provide SDKs for different high-level languages to wrap the obscure things.

The 1st language we want to support is JavaScript, the most popular one of today. But we cannot do that because there's still not a good compiler to compile JavaScript to WebAssembly.

The alternative choice for JavaScript is AssemblyScript, which is a variant of TypeScript, has similar syntax with JavaScript and was designed for WebAssembly.
