Advantages of React Stateless Functional Components
Before reading this post, if you have not gone through what are functional components in Reactjs then kindly go through this post
In this post we will see what are the advantages of functional posts in React js. If you check your react js code, you will quickly figure out that many components do not actually need state, they do get data from parent as props and will render the information. In such a case why to introduce state and make it complicated? rather I would prefer calling a function which returns me a component. Isn’t it so simple ? React 14 introduced Functional Components, also called as stateless components and removed unnecessary complications. So let us explore what are the advantages of stateless components
Advantages of React Functional/Stateless Components: Ref
1. More focused on presentation
React is forcing us to write components which are used only for presentational purpose, these components are useful for dumb presentational purpose only, that focus on UI rather than behaviour. Technically speaking its normal tendency to go for stateful components, doing that way we are making our code easily hackable where every damn component keeps its own local state. Functional components allowing us to have pure components which just focus on presentation. where as the state is maintained by few higher level components.
2. Gain in Performance
Stateless components will bring performance gain since there is no state and lifecycle of a component. React doesn’t need to have unnecessary check and memory allocations which eventually brings performance boost.
3. Clean and Optimised Code
Stateless components reduce lot of code, almost 20% – 30% reduction in code and hence the code will become clean and optimised.
4. Easy to debug
Functional components are pure components and helps your to analyse your code quickly and you no need to put log if assert calls everywhere to debug.
