React has become one of the most popular frameworks in web development today. It avoids the need to perform complex DOM manipulation, helps focus development on more advanced implementations, and improves efficiency in user experiences.

Components play an important role in React. They are the building blocks of any React application. They are independent and reusable code. They serve the same purpose as JavaScript functions, but work in isolation and return JSX code as elements for our UI.

Today, I will briefly talk about four different types of React components.

  • Class Component
  • Pure Component
  • Higher Order Component

How do we improve our problem solving?

Today, security plays an important role in our internet world. Whether we just casually browse on some shopping websites, or sign in to our bank accounts to check balances, site security should always protect our information privacy and prevents data being leaked.
