Normalize array to unit length, that is 0..1 range. See [feature scaling](https://en.wikipedia.org/wiki/Feature_scaling).
[](https://npmjs.org/package/array-normalize/)
```js
const normalize = require('array-normalize')
normalize([0, 50, 100]) // [0, .5, 1]
normalize([0, 0, .1, .2, 1, 2], 2) // [0, 0, .1, .1, 1, 1]
normalize([0, .25, 1, .25], 2, [0, .5, 1, .5]) // [0, .5, 1, .5])
```
## API
### array = normalize(array, dimensions=1, bounds?)
Normalizes n-dimensional array in-place using `dimensions` as stride, ie. for 1d array the expected data layout is `[x, x, x, ...]` for 2d is `[x, y, x, y, ...]`, etc.
Every dimension is normalized independently, eg. 2d array is normalized to unit square `[0, 0, 1, 1]`.
Optional `bounds` box can predefine min/max to optimize calculations.
