JavaScript evolved from simple browser scripting to become the primary language for Web3 development. Libraries like ethers.js and web3.js enabled browsers to interact directly with blockchains, transforming frontends into financial applications. Node.js powers deployment scripts, testing, and infrastructure integration across the Web3 stack. While JavaScript wasn't designed for financial logic, it became the universal bridge between smart contracts, APIs, and user interfaces. Frontend developers brought modern UX to decentralized apps, making blockchain accessible beyond command-line interfaces. Modern tools like viem, wagmi, and TypeScript are making Web3 development safer and more modular.
