Lifecycle Methods in React Class Components
Understanding Lifecycle Methods in React Class Components
React, a popular JavaScript library for building user interfaces, provides a robust framework for managing the lifecycle of components. In class components, lifecycle methods are crucial for handling the birth, growth, and death phases of components. These methods offer hooks into specific points during a component’s lifecycle, allowing developers to control components effectively, perform side-effects, fetch data, and manipulate the DOM.
The Lifecycle of a React Component
The lifecycle of a React class component can be divided into three main phases:
Mounting: When the component is being created and inserted into the DOM.
Updating: When the component is being re-rendered as a result of changes to either its props or state.
Unmounting: When the component is being removed from the DOM.
