+Parser-JS API implements a global API definition for all AsyncAPI parser implementations known as the [Parser-API](https://github.com/asyncapi/parser-api). This API is designed having in mind developer experience and resiliency to breaking changes.
 
 The following table shows a compatibility matrix between this parser, and the [Parser-API](https://github.com/asyncapi/parser-api), as well as the AsyncAPI spec version supported by each release of this parser.

 - `-` The AsyncAPI Spec version has features the Parser-JS can't use but the rest are fully supported.
 - Empty means not supported version.

+- `json()` which returns the JSON object of the given object. It is possible to pass as an argument the name of a field in an object and retrieve corresponding value.
+- `jsonPath()` which returns the JSON Path of the given object.
+- `meta()` which returns the metadata of a given object, like a parsed AsyncAPI Document.
