I want to have the max date from the list of dates given in the handleClick function. How to find the max date from the list of dates using moment.js?

I have the following code:

import React, {Component} from 'react';

class Getdate extends Component
{
  constructor() {
    super();
    this.state = {
       dates = []
    }
    this.handleClick = this.handleClick.bind(this);
  }
  handleClick() {
     this.state.dates = ['2017-11-12', '2017-10-22', '2015-01-10', '2018-01-01', '2014-10-10'];
     console.log(this.state.dates);

  render{
    return (
     <button onClick={this.handleClick}>Get Max Date</button>
    )
  }
}
export default Getdate

Answer 1

You can use moment.max function :

let moments = this.state.dates.map(d => moment(d)),
    maxDate = moment.max(moments)
