# Compiler assumptions
|
|
|
|
Babel and its associated official transforms make some assumptions about your code. These
|
|
assumptions are only made as they're either **impossible** to take into consideration or
|
|
are extremely exotic.
|
|
|
|
- `undefined`, `NaN` and `Infinity` have not been externally redefined.
|
|
- Built-in objects such as `Object`, `Array`, `String`, `Number`, `Boolean` etc have not been redefined.
|
|
- Standard methods on built-ins have not been redefined in a way that breaks the original contract.
