# Random Cannot Be Seeded
In JavaScript, you can use `Math.random()` to get a *sorta* random value.
```javascript
> Math.random()
0.5130641541909426
```
Most programming languages give you a method of seeding the random number
generator for determinism. Unfortunately, JavaScript provides no way for
choosing or resetting the seed to `Math.random()`.
