A jsonpath parser.
fastPath 
An attempt at an optimized jsonpath parser
Check the spec here: http://goessner.net/articles/JsonPath/
Use
var fastpath = require('fastpath');
var matcher = fastpath(pattern);
// or
var matcher = fastpath({
name: pattern,
name2: pattern2
});
matcher.evaluate(object);
| Pattern | Description |
|---|---|
| $ | the root object/element |
| @ | the current object/element |
| . or [] | child operator |
| .. | recursive descent |
| * | wildcard - All objects/elements regardless of their names |
| [] | Native array operator |
| [,] | Names or array indices |
| [start : end : step] | Slices subset of the array based on the start, end and step values |
| ?() | applies a filter |
The tape tests have most of the patterns supported by the spec.
