lifecycle of class component in react code example
Example 1: componentDidUpdate
componentDidUpdate(prevProps, prevState) {
if (prevState.pokemons !== this.state.pokemons) {
console.log('pokemons state has changed.')
}
}
Example 2: lifecycle methods react
Every component in React goes through a lifecycle of events. I like to think of them as going through a cycle of birth, growth, and death.
Mounting – Birth of your component
Update – Growth of your component
Unmount – Death of your component
Example 3: component did mmount
componentDidUpdate(prevProps, prevState, snapshot)
Example 4: react lifecycle
constructor(props) {
super(props);
this.state = { counter: 0 };
this.handleClick = this.handleClick.bind(this);
}
