Comparison of Function Components and Class Components in React.js
1. Comparison of Function Components and Class Components in React.js
Classes and functions can both be used to create components in React.js. Each approach has its
advantages and use cases.
Function Components:
● Simplicity: Function components are generally simpler and easier to understand. They are
just JavaScript functions that take props as input and return React elements.
● Performance: React's built-in features, like as memoization and hooks, can be used to
optimise the performance of function components.
● Hooks: React's introduction of hooks has given function components the same capability
as class components by enabling them to have state and side effects.
● Readability: Since the introduction of hooks like useState and useEffect, they have
become easier to understand and readable.
Class Components:
● Lifecycle methods: ComponentDidMount, ComponentDidUpdate,
ComponentWillUnmount
● Class Properties: Initial State and other class properties can be defined directly within a
class definition.
● Hierarchy/Inheritance: Class components extend other components, making it easier to
implement inheritance and composition patterns
● Experience: Some developers may better understand class-based syntax than others,
especially if they have experience in OOP.
