JavaScript is the primary language for most web3.js applications. Developers also use TypeScript when they want code that is easier to review and maintain. You’ll still likely need Solidity for Ethereum smart contracts, but web3.js lets you build the user-facing parts of dApps in JavaScript or TypeScript. For backends or automation, you may use Python or Go, but the web front-end usually runs on JavaScript.
