# JSN - Fast low allocation JSON library
|
||
|
|
## Design
|
||
|
|
|
||
|
|
This libary is designed as a set of seperate functions to extract data and mutate
|
||
|
|
JSON. All functions are focused on keeping allocations to a minimum and be as fast
|
||
|
|
as possible. The functions don't validate the JSON a seperate `Validate` function
|
||
|
|
does that.
|
||
|
|
|
||
|
|
The JSON parsing algo processes each object `{}` or array `[]` in a bottom up way
|
||
|
|
where once the end of the array or object is found only then the keys within it are
|
||
|
|
parsed from the top down.
|
||
|
|
|
||
|
|
```
|
||
|
|
