#web3react

Today we will discuss the Web3JS library, its history, maintenance, and community involvement. The upcoming version 4 aims to address challenges faced in version 1 by introducing native TypeScript support, reduced size, improved code readability, and increased test coverage. Version 4 also introduces a new validator for easier Ethereum data validation and allows developers to customize how they handle numbers and bytes. It brings a dynamic data format for custom formatting and introduces TypeScript for contracts without transpiling. The API in version 4 is easy to extend and has future improvements and refactoring.
