Usage

import React, { Component } from 'react';
import IgnoreRerender from 'react-ignore-rerender';

class ExampleComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      showTitle: false,
      showDescription: false,
    };
  }
  render () {
    const {showTitle, showDescription} = this.state;
    return (
      <IgnoreRerender whiteList={{ showTitle, showDescription }}>
        { showTitle && <h1>Title</h1> }
        { showDescription && <p>Description</p> }
