react js component lifecycle methods code example

Example 1: 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 2: shouldcomponentupdate

shouldComponentUpdate(nextProps, nextState) {
  return true;
}

Example 3: component did mmount

componentDidUpdate(prevProps, prevState, snapshot)
