+class JSONDict(dict):
+    """
+    A dictionary-like class that provides JSON persistence for its contents.
+
+    This class extends the built-in dictionary to automatically save its contents to a JSON file whenever they are
+    modified. It ensures thread-safe operations using a lock.
+
+    Attributes:
+        file_path (Path): The path to the JSON file used for persistence.
+        lock (threading.Lock): A lock object to ensure thread-safe operations.
+
+    Methods:
+        _load: Loads the data from the JSON file into the dictionary.
+        _save: Saves the current state of the dictionary to the JSON file.
+        __setitem__: Stores a key-value pair and persists it to disk.
+        __delitem__: Removes an item and updates the persistent storage.
+        update: Updates the dictionary and persists changes.
+        clear: Clears all entries and updates the persistent storage.
+
+    Examples:
+        >>> json_dict = JSONDict("data.json")
+        >>> json_dict["key"] = "value"
+        >>> print(json_dict["key"])
+        value
+        >>> del json_dict["key"]
