title_body: Are there web3.js-like in Cardano? With the Cardano's Alonzo Hard fork coming, the Cardano testnet will be coming in. I assumed that there is a frontend library for interacting with the Cardano testnet, however I couldn't find anywhere. I wonder if there are libraries that are being developed?
  Regards,
  Ivan
upvoted_answer: There isn't currently a Javascript library, but it looks like the Cardanoscan folks are building one for interfacing with the Cardano blockchain (link to article).
  The current pioneer's testnet for writing smart contracts uses Plutus. You can read more about this here.
