A JavaScript runtime using V8 6.8 and Go.
A secure TypeScript runtime on V8
* Supports TypeScript 2.8 out of the box.
* Supports TypeScript 2.8 out of the box. Uses V8 6.8.275.3. That is, it's
very modern JavaScript.
* No package.json, no npm. Not backwards compatible with Node.
* No package.json, no npm. Not explicitly compatible with Node.
* Imports reference source code URLs only.
```
import { test } from "https://unpkg.com/deno_testing@0.0.5/testing.ts"
import { log } from "./util.ts"
```
Remote code is fetched and cached on first execution, and never updated until
the code is run with the `--reload` flag. (So this will still work on an
airplane. See `~/.deno/src` for details on the cache.)
* File system and network access can be controlled in order to run sandboxed
code. Defaults to read-only file system access. Access between V8
(unprivileged) and Golang (privileged) is only done via serialized messages
defined in this protobuf: https://github.com/ry/deno/blob/master/msg.proto
This makes it easy to audit.

To enable write access explicitly use `--allow-write` and `--allow-net` for
network access.

Installing `v8worker2` is time consuming, because it requires building V8. It
may take about 30 minutes:
You need to get and build `v8worker2`. It takes about 30 minutes to build:
```
go get -u github.com/ry/v8worker2
cd $GOPATH/src/github.com/ry/v8worker2
./build.py --use_ccache
```
You might also need Node and Yarn.
Finally the dependencies are installed.
Finally you can get `deno` and its other Go deps.
```
go get -u github.com/ry/deno/...
```
Now you can build deno and run it:
```
> cd $GOPATH/src/github.com/ry/deno
> make

> ./deno testdata/001_hello.js
