## Description

WebViewJavascriptBridge is a communication layer for sending bidirectional messages between native Objective-C code and JavaScript within iOS and macOS web views. It serves as an interoperability toolkit for synchronizing data and executing callbacks between native Apple platform applications and their embedded web content.

The project provides a messaging interface that exposes native functions to the web environment and triggers JavaScript handlers from native application code. It enables the registration of named handlers in native code that can be invoked by JavaScript to request device actions.

The bridge manages communication through a named handler registry and a system for callback-based response routing. It utilizes mechanisms such as URL-scheme message passing and string-evaluation execution to facilitate the exchange of data between the native layer and the web view.
