Web3.js

How do web3.js developers implement smart contracts?

The question is about Web3.js .

Answer:
Web3.js developers interact with Solidity smart contracts using the contract's ABI and deployed address. They read contract data and send transactions to invoke contract functions. Before going live, both the JavaScript code and the smart contract should be tested on a testnet. After deployment, it is important to audit the smart contracts carefully, as changes are difficult once they are live.
