Hello @sudheerj , thank you for this wonderful collection of questions! Here are some of my comments to improve the document:

• Duplicity: 82 and 109
  82 and 109 are almost the same and can be considered as duplicate ( 82: "Why we need to pass a function to setState()?" - 109: "Why function is preferred over object for setState?" )
• Duplicity: 87 and 118
  87 and 118 refer to a very similar topic and can be merged ( 87: "Why should component names start with capital letter?" - 118: "Why React component names must begin with a capital letter?" )
• 102: "How to listen to state changes?"
  componentWillUpdate is deprecated.
• 182: "What are Redux selectors and why to use them?"
  I think why to use them is not mentioned. One specific need is when using them with "select" method of saga's.
• 205: How to use TypeScript in create-react-app application?
  create-react-app now supports TypeScript natively: see: https://github.com/wmonk/create-react-app-typescript
• 208: What is an action in Redux?
  Should go under redux section instead of misc.
• 209: Does the statics object work with ES6 classes in React?
  There is a third way of writing statics; that is, outside the class:

class Component extends React.Component {
   ....
}

Component.propTypes = {...}
Component.someMethod = function(){....}

• 215: Why are inline ref callbacks or functions not recommended?
  There is no need to use both since React.createRef brought with v16.3 is much neater than both: https://reactjs.org/blog/2018/03/29/react-v-16-3.html#createref-api
• 226: "What are hooks?"

Hooks are a new feature proposal that lets you...

Hooks are no more a proposal
