Question

I am using react-datepicker NPM package,
I tried to follow documentation but I was unable to import

registerLocale 

and

Answer 1

import React, { Component } from 'react';
import DatePicker, { registerLocale } from "react-datepicker";
import "react-datepicker/dist/react-datepicker.css";
import ja from "date-fns/locale/ja";

registerLocale("ja", ja);

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      date: new Date()
    }
    this.handleChange = this.handleChange.bind(this);
  }

  handleChange(date) {
    this.setState({
      date
    });
  }

  render() {
    return (
      

        
          
        
      
    );
  }
}

export default App;

I could get the result you wanted. And I tried to make it with moment library but it didn't work on my code. sorry
