## 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.

<b>Signature:</b>

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

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  ctx | <code>Context</code> | Context for the resolution |
|  session | <code>ResolutionSession</code> | Optional session for binding and dependency resolution |

<b>Returns:</b>

`ValueOrPromise<T>`

## Example


```
const result = binding.getValue(ctx);
if (isPromiseLike(result)) {
  result.then(doSomething)
} else {
  doSomething(result);
}

```
