```
server.Server.hasSession(name: : string) -> Promise<boolean>
```

Whether a session with this name exists.

The name is matched exactly. tmux normally accepts a unique prefix as a
session target, which would make checking `work` answer yes for
`workspace`; this method does not.

## Example

```ts
if (!(await server.hasSession("work"))) {
  await server.newSession({ name: "work" });
}
```
