Example

use jsonc_parser::cst::CstRootNode;
use jsonc_parser::ParseOptions;
use jsonc_parser::json;

let json_text = r#"{
  // comment
  "data": 123
}"#;

let root = CstRootNode::parse(json_text, &ParseOptions::default()).unwrap();
let root_obj = root.object_value_or_set();

root_obj.get("data").unwrap().set_value(json!({
  "nested": true
}));
root_obj.append("new_key", json!([456, 789, false]));

assert_eq!(root.to_string(), r#"{
  // comment
  "data": {
    "nested": true
  },
  "new_key": [456, 789, false]
}"#);
