How to implement lifecycle methods in functional components in React?

Question

For a simple component written like this:

import React from 'react'

const MyComponent = ({text}) => {
    return(<div> {text} </div>
}

Is there a syntax for implementing lifecycle method like componentDidMount() or do I have to convert code to React.Component class?
