How do Vue JS and Metamask web relate to each other?

edit

Vue JS is a front-end JavaScript framework for building user interfaces, while MetaMask is a browser extension that allows users to interact with Ethereum blockchain applications.

Vue JS can be used to build web applications that interact with the Ethereum blockchain and MetaMask can be used as the web3 provider for these applications. This means that Vue JS can use MetaMask as a web3 provider to connect to Ethereum and handle transactions, manage accounts, interact with smart contracts, and more.

By integrating MetaMask with Vue JS application, users can securely connect their Ethereum accounts with the application, without having to expose their private keys to the application itself. The user can then use the application to interact with the blockchain directly from their MetaMask extension.
