Generate new Ethereum Wallet in NodeJS

Question

Are you familiar with Ethereum and web3js-API in node js?

I used the framework sails, and I am a little bit confused about how to generate a new account. For now i used web3js-API v.1.0.0. I can get the current account and balance. I try to create a new account, but it returns an error, saying create is not a function, etc.

I used testnet, how can I connect it to metamask (Rinkeby Network)? So if I generate a new account, the account will appear in the metamask account list also.

If you know, please share. Thanks.

 In its simplest form, the Ethereum wallet is just a single private key that generates a random 256-bit integer - which is your private key/ The web3.js functions can import any private key with privateKeyToAccount - Which will derive an Ethereum public key and Ethereum address, which is just a trimmed public key, for you. Now web3.js can use your private key to sign transactions and messages. Learn more about Blockchain and its concepts from the Blockchain developer course.
