In this article we are reading about  “ Understanding the React Component Lifecycle ”. React  enables to create components by invoking the React.createClass() method which expects a  render  method and triggers a lifecycle that can be hooked into via a number of so called lifecycle methods. Understanding the component lifecycle will enable you to perform certain actions when a component is created or destroyed. Further more it gives you the opportunity to decide if a component should be updated in the first place and to react to props or state changes accordingly. We know that ReactJS is a component based javascript library. In every ReactJS application components are rendered onto virtual DOM. Before/After rendering onto the virtual DOM every component goes through some of the methods. We call these methods as ReacjJS Component Lifecycle Methods. We can categorize these methods into three based on component initialization, updation and destruction. They are ...

In this article we are reading about  “ States and Props in ReactJS ”. Dynamic apps must need to pass data around it’s system. In React, data movement happens mostly among components and external services that provide the original data (eg HTTP, localStorage). Props are immutable and dumb which means they can only be passed from parent components down and cannot be changed. This poses a challenge because, modern apps do not rely on having all of it’s states ready on page load. Ajax or Events could happen and when data returns, someone needs to be responsible for making updates. This is where React states comes in. On initializing React, we define an initial state and keep the state in sync with the props. Once the state is updated, the props can then be easily kept in sync: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 //js var  Counter  =  React. createClass ( { getInitialState :   function ( ) ...
