Namespacing

[connor4312]

Described pretty well, with an example, in the Namespace class:

Namespace is the class on which CRUD operations can be invoked. The default
namespace is the empty string, "". You can create nested namespaces by
calling the namespace(prefix) method.

For example, if the current namespace is the default "" and you call
namespace('user1/'), all operations on that new namespace will be
automatically prefixed with user1/:

const client = new Etcd3();
const ns = client.namespace('user1/');

await ns.put('foo').value('bar'); // sets the key `user1/foo` to `bar`
await ns.delete().all(); // deletes all keys with the prefix `user1/`

Namespacing is particularly useful to avoid clashing between multiple
applications and when using Etcd's access control.

You can use destructuring here.

Discussed in person, destructuring doesn't type well with generics
