Performance optimization is crucial for ensuring that React applications are fast and responsive, providing a smooth user experience. In this article, we'll explore various techniques and best practices for optimizing the performance of React applications.
React provides a series of lifecycle methods that allow developers to hook into different stages of a component's lifecycle. These methods vary between functional and class components due to the differences in their nature.
React is uni-directional in the sense that data flows in a single direction, from the parent component to its children components, through the use of props.
In JavaScript, when you create a new object and assign it to a variable, the object is stored in memory and the variable points to the memory location where the object is stored.
The useState hook is a feature in React that allows you to manage state in your components. State is a way to store and manage data that can change over time, and it is an important aspect of any dynamic user interface.
