How do I optimize my React app?
Some ways to optimize the performance of react js apps might include:
- Using Immutable Data Structures.
- Function/Stateless Components and React.
- Multiple Chunk Files.
- Avoid Inline Function Definition in the Render Function.
- Throttling and Debouncing Event Action in JavaScript.
- Avoid using Index as Key for map.
What makes Reactjs performance faster?
Using immutable data is one of the best ways to improve react js apps performance, Immutable data allows you to compare direct object references instead of doing deep-tree comparisons thus making the app really fast.
Can lazy loading make react js apps better optimized ?
In essence, lazy loading means that a component or a part of code must get loaded when it is required. It is also referred to as code splitting and data fetching . Talking about React specifically, it bundles the complete code and deploys all of it at the same time.
What is used in React JS to increase performance?
React. memo() boosts the performance of a React app by avoiding re-rendering components whose props haven't changed or when re-rendering is not needed.
