Learning Goals:

This lab aims to target the concept of Pure Components.

Introduction:

The task is simple, you have to create a counter functionality using class component. The only condition is that -> you can only increament the counter -> if the value of toggle is true, where toggle is a boolean type variable - which changes it's value between true/false, everytime you click on the Set toggle button. Initially the value of toggle should be false; and you can set the value of toggle to be true by clicking on a button called Set toggle. Once the value of toggle is true, you can increament the counter by one -> by clicking on the increament button, as shown below.

Your task is to implement, the above problem statement using class component which extends -

1. Component
2. PureComponent

Steps to follow:

1. create a new react app.

2. inside src folder, create a new folder components.

3. inside components folder, create two components -

   1. SimpleCounterComponent.jsx
   2. PureCounterComponent.jsx

4. inside SimpleCounterComponent.jsx, you create a counter functionality as described above using class component. In this component, the class should extend Component.

5. inside PureCounterComponent.jsx you create a counter functionality as described above using class component. But in this case, extend the class with Pure Component.

6. Render both the components inside App.jsx.

Question:

As mentioned before, this lab is all about targeting the idea of Pure Components, so after completeing the above task answer the question given below->

1. Inside SimpleCounterComponent.jsx -> after you render and before you return the jsx --> print out the following --> console.log(This is Simple Component) ie:

   class SimpleCounterComponent extends Component {
   
    <!-- your logic for the above problem -->
   
    render(){
      console.log("This is Simple Component")
      return(
   
        <!-- your jsx for the above problem -->
   
      )
    }
   }

2. Similarly, console.log(This is Pure Component), inside PureCounterComponent.jsx file.

You will see your console, in the similar manner as shown below:

Question: Which out of the two components (which are performing the same functionality) is performing better and how?

You can write your answer by creating a new markdown file, named as -> Answer.md, inside the src folder.

Happy Coding ❤️!
