Solidity Vs Javascript

JavaScript and Solidity are two different programming languages that are used for different purposes.
JavaScript is a high-level, dynamic programming language that is commonly used to develop web applications. It is primarily used for front-end development, but it can also be used for back-end development using technologies such as Node.js. JavaScript is widely used for building interactive elements on websites, such as drop-down menus, form validation, and creating games.
Solidity is a programming language for writing smart contracts on the Ethereum platform. It is a statically-typed language that is designed specifically for use in the context of Ethereum and other blockchain platforms. Solidity is used to write contracts that can be executed on the Ethereum Virtual Machine (EVM), which is the runtime environment for Ethereum. Solidity is used to create decentralized applications (DApps) that are run on a blockchain.
While both JavaScript and Solidity are used to write code that can be executed by a computer, they are used for different purposes and have different syntax and features.
With good knowledge in Javascript, you can easily switch to solidity as the case may be. However, you still need to study the new syntax and familiarize yourself with it.
