Both web3.eth.accounts.create() and web3.eth.personal.newAccount() not working

Question

I'm making a dApp on reactjs. I wanted to create a new account and have done it trying 2 methods

1. this.web3.eth.personal.newAccount()
2. this.web3.eth.accounts.create()

I have attached the code below(ignore the comments)

 OTPSubmit(event) {
     event.preventDefault();
     //alert('A name was submitted: ' + this.state.value);
     this.setState({
        showComponent: true,
       account: this.web3.eth.personal.newAccount()
       #account: this.web3.eth.accounts.create()
     });

   }

These are the errors I'm getting

1. web3.eth.accounts.create() is not a function
2. Cannot read property 'newAccount' of undefined

Can you please help me? I am very new to this

if you are using web3.js 1.0.0, try giving a password in the parameters like this:

web3.personal.newAccount(newPassword);

if you are using an older version, try to separate "password" and "callback result" arguments like "Hamid Jolany" mentionned in this post:

web3.eth.personal.newAccount(password,(result)=>{ console.log(result); res.send(JSON.stringify(result));
});
