However, in some areas, performance concerns make this prohibitively expensive, so some compromises are made. Also, there is a general preference against [nasal demons](https://en.wikipedia.org/w/index.php?title=Nasal_demons), since they are an extreme on the spectrum of observable differences, and since they make it difficult to reason about what state an application might be in. WebAssembly usually prefers to [trap](AstSemantics.md). Otherwise, it is generally preferred to have a specific set of possible behaviors rather than nasal demons. And presently, WebAssembly has no nasal demons. |
