When working with web3.js, JavaScript is the main programming language, as web3.js is a JavaScript library. You often also need Solidity to write Ethereum smart contracts that web3.js interacts with. TypeScript can be used for type safety when building dApps. Sometimes, developers connect web3.js apps to backend languages such as Python or Go, but JavaScript and Solidity are the primary choices.
