Legacy JavaScript client

The project was superseeded by 2 new official Telegram Web Apps: https://github.com/morethanwords/tweb - Telegram Web K, based on source code of Webogram, rewritten in TypeScript. https://github.com/Ajaxy/telegram-tt - Telegram Web Z, based on its own Teact framework (which re-implements React paradigm), uses a custom version of GramJS as an MTProto implementation. Written also in Typescript.
