## Binding.getValue() method

This is an internal function optimized for performance. Users should use `@inject(key)` or `ctx.get(key)` instead.

Get the value bound to this key. Depending on `isSync`<!-- -->, this function returns either: - the bound value - a promise of the bound value

Consumers wishing to consume sync values directly should use `isPromiseLike` to check the type of the returned value to decide how to handle it.

**Signature:**

```typescript
getValue(ctx: Context, session?: ResolutionSession): ValueOrPromise<T>;
```
