### Casting - Safe Scenarios

Source: https://github.com/graphprotocol/docs/blob/main/website/src/pages/en/resources/migration-guides/assemblyscript-migration-guide.mdx

Examples of safe casting using the 'as' keyword or angle brackets in AssemblyScript.

```typescript
let byteArray = new ByteArray(10)
let uint8Array = byteArray as Uint8Array // equivalent to: <Uint8Array>byteArray
```

```typescript
// primitive casting
let a: usize = 10
let b: isize = 5
let c: usize = a + (b as usize)
```

```typescript
// upcasting on class inheritance
class Bytes extends Uint8Array {}

let bytes = new Bytes(2)
// <Uint8Array>bytes // same as: bytes as Uint8Array
```
