# Ice For JavaScript
[Getting started] | [Examples] | [NPM packages] | [Documentation] | [Building from source]
The [Ice framework] provides everything you need to build networked applications,
including RPC, pub/sub, server deployment, and more.
Ice for JavaScript is the JavaScript implementation of the Ice framework.
## Sample Code
```slice
// Slice definitions (Hello.ice)
module Demo
{
interface Hello
{
void sayHello();
}
}
```
```javascript
// Client application (client.js)
let communicator;
try
{
communicator = Ice.initialize(process.argv);
const hello = await Demo.HelloPrx.checkedCast(
communicator.stringToProxy("hello:tcp -h localhost -p 10000"));
await hello.sayHello();
}
catch(ex)
{
console.log(ex.toString());
}
finally
{
if(communicator)
{
await communicator.destroy();
}
}
```
