# Return value

Return value is the result directly obtained after executing a [unit of code](https://blog.fiftywords.co/unit-of-code), usually denoted by the reserved word ```return```

It's the easiest [exit point](https://blog.fiftywords.co/exit-point) to verify because, after getting the value returned by the [unit of code](https://blog.fiftywords.co/unit-of-code), we can compare it with the expected result.

```ts
/** 
 * It's common to point the return type in the entry point (signature)
 * In this case is the last ```number``` that specifies 
 * what type this unit of code returns.
 */
function add(summand: number, otherSummand: number): number {
  /** Return value exit point */
  return summand + otherSummand;
}
```
