The cn2tw4programmer is a Chrome extension designed to assist users in translating commonly used computer science terms from Simplified Chinese (zh-CN) to Traditional Chinese (zh-TW). Unlike typical translation tools, this extension focuses specifically on technical vocabulary, helping users understand terms like '數組' as '陣列' and '對象' as '物件'. This targeted approach makes it invaluable for programmers and developers who often encounter these terms in their work.

In addition to its core functionality, the extension offers compatibility with the new Tongwen Tang dictionary files available on GitHub, allowing for easy importation of additional terms if needed. Users can also contribute to the project by submitting pull requests for new or modified vocabulary, enhancing the tool's utility for the programming community.
