Web3.js

What’s the difference between connecting web3.js to a public Ethereum network or a private chain?

The question is about Web3.js .

Answer:
When you use web3.js with the public Ethereum network, anyone can access it, send transactions, and deploy contracts. Everything is visible to everyone. With a private chain, only selected users or organisations have access - usually for a specific project or within a business. Private networks let you control who can use them, but you may lose some benefits of openness and decentralisation.
