    Let’s read about each Web3 language in detail below.

    1) Solidity:

    Smart contracts for Ethereum are written in Solidity, a high-level language designed for the Ethereum Virtual Machine (EVM). Solidity serves as a web3 programming language of the blockchain world. It is specially designed for creating smart contracts. You can also create self-executing contracts with pre-defined rules on Ethereum and other similar platforms.

    What are smart contracts?

    Some programs are written in blockchain to ensure security and transparency are called smart contracts. They are self-executing contracts with pre-defined conditions written in code.

    It is a tool used to write the rules and functions governing these contracts. It defines how they should operate. On the other hand, web3 represents a set of libraries and tools that allow communication between applications and the blockchain.

    Together, solidity and Web3 enable the creation of decentralized systems that run without a central authority. They allow developers to build apps that don’t rely on a single entity. However, a network of computers is crucial for sustainability. So, this technology promises a future where transactions are transparent.

    2) JavaScript:

    This web3 programming language is widely used for frontend development of decentralized applications, typescript, a superset of JavaScript. It is gaining popularity because of its safety features. In the world of Web3 JavaScript programming language  plays a crucial role. It is used for interacting with blockchain networks and decentralized applications (dApps).

    With Web3 libraries like Web3.js, JavaScript facilitates communication between browsers and blockchain networks like Ethereum. It allows developers to build interfaces, connect to smart contracts, and enable user interaction within dApps.

    JavaScript has the power to enable developers to create an intuitive and user-friendly interface for decentralized applications. Though functions are provided by Web3 libraries, developers can manage user wallets, send transactions to the blockchain, and interact seamlessly with smart contracts.
