A schema is essentially a blueprint or a predefined structure that defines the expected format, data types, and constraints for a given data entity. In this blog, we will delve into the concept of schemas in Python, exploring what they are, why they are important, and how you can implement them in your projects. What is a Schema?

It defines the rules for how data should be organized, what fields it should contain, and what types of values those fields can hold.

Basically, props are passed to component via HTML attribute. Passing props within a tree of a components is known to be Prop drilling. Prop drilling The above image describe the problem of prop drilling. The top component "ComponentA" and bottom component "ComponentD" are accessing the actual state but both middle components "ComponentB" and "ComponentC" are just passing state. This is actually problem of Prop-Drilling. Sample code: import   React , {  useState  }  from   'react' ; export   default   function   App () {    return  (      <>        < h1 > Prop Drilling </ h1 >        < ComponentA   />      </>   ); } function   ComponentA () {    const  [ name ,  setName ] =  useState ( 'vijay' );    return   < ComponentB
