([/ˈdiːnoʊ/](http://ipa-reader.xyz/?text=%CB%88di%CB%90no%CA%8A), pronounced
`dee-no`) is a JavaScript, TypeScript, and WebAssembly runtime with secure
defaults and a great developer experience. It's built on [V8](https://v8.dev/),

### Build and install from source
Complete instructions for building Deno from source can be found in the manual
[here](https://docs.deno.com/runtime/manual/references/contributing/building_from_source).
## Your first Deno program
2020-09-29 15:40:17 +00:00
Deno can be used for many different applications, but is most commonly used to
build web servers. Create a file called `server.ts` and include the following
TypeScript code:
```ts
Deno.serve((_req: Request) => {
return new Response("Hello, world!");
});
2020-09-29 15:40:17 +00:00
```
Run your server with the following command:
2020-09-29 15:40:17 +00:00
```sh
deno run --allow-net server.ts
2020-09-29 15:40:17 +00:00
```
This should start a local web server on
[http://localhost:8000](http://localhost:8000).
