How to create a public key and private key using web3js ?

[zororaka]

I am learning to use web3js in this case to create an ethereum address and a private key to make a simple dapp.

Can anyone tell me to use this web3js? If you are pleased, I ask for help on how to use it

My achievement recently studied to see the balance of ethereum and token ERC20.

To further solidify this post, maybe there are also people who can share information about web3js as a reference for me and others who see this post

i never tried myself as i think it may be better and safe use some other recognized way to create new accounts (metamask or myetherwallet) however here is what you are looking for https://web3js.readthedocs.io/en/1.0/web3-eth-accounts.html

If use it separately like using json-rpc, does anyone know where the complete reference is ?
