+pkpy has two JSON modules.
|
|
|
+1. The built-in JSON module is always available and can be imported via `import json`.
|
|
|
+2. After `v1.2.7`, you can set `PK_USE_CJSON` to `ON` in CMakeLists.txt to enable an alternative JSON module `cjson`.
|
|
|
+
|
|
|
+Their interfaces are the same, `cjson` is faster while the built-in `json` is more stable since it was developed earlier.
