Now that’s out of the way, we’ve got two ways (currently) to create a React component:

A pure function: no lifecycle hooks

As a class: has lifecycle hooks

What are React lifecycle hooks?

They’re functions implemented by React.Component that we get to override and make use of. You can find a simple example here.

	import React from 'react';
	import moment from 'moment';
	import DayPicker, { DateUtils } from 'react-day-picker';

	export default class MydateFilter extends React.Component {
	constructor(props) {
	super(props);
	this.handleDayClick = this.handleDayClick.bind(this);
	this.handleResetClick = this.handleResetClick.bind(this);

	'use strict';

	Object.defineProperty(exports, "__esModule", {
	value: true
	});

	var _extends = Object.assign \|\| function (target) { for (var i = 1; i < arguments.length; i++) { var source = arguments[i]; for (var key in source) { if (Object.prototype.hasOwnProperty.call(source, key)) { target[key] = source[key]; } } } return target; };

	var _slicedToArray = function () { function sliceIterator(arr, i) { var _arr = []; var _n = true; var _d = false; var _e = undefined; try { for (var _i = arr[Symbol.iterator](), _s; !(_n = (_s = _i.next()).done); _n = true) { _arr.push(_s.value); if (i && _arr.length === i) break; } } catch (err) { _d = true; _e = err; } finally { try { if (!_n && _i["return"]) _i["return"](); } finally { if (_d) throw _e; } } return _arr; } return function (arr, i) { if (Array.isArray(arr)) { return arr; } else if (Symbol.iterator in Object(arr)) { return sliceIterator(arr, i); } else { throw new TypeError("Invalid attempt to destructure non-iterable instance"); } }; }();

	'use strict';

	Object.defineProperty(exports, "__esModule", {
	value: true
	});

	var _createClass = function () { function defineProperties(target, props) { for (var i = 0; i < props.length; i++) { var descriptor = props[i]; descriptor.enumerable = descriptor.enumerable \|\| false; descriptor.configurable = true; if ("value" in descriptor) descriptor.writable = true; Object.defineProperty(target, descriptor.key, descriptor); } } return function (Constructor, protoProps, staticProps) { if (protoProps) defineProperties(Constructor.prototype, protoProps); if (staticProps) defineProperties(Constructor, staticProps); return Constructor; }; }();

	var _react = require('react');
