- Avoid using
PropTypes.stringfor a prop that sets a type/variation, usePropTypes.oneOf(CONSTANT)instead:
// BAD:
Button.propTypes = {
size: React.PropTypes.string
};
// Good:| package com.company; | |
| public class Main { | |
| public static void main(String[] args) { | |
| // write your code here | |
| // apelle de la methode | |
| System.out.println(somme(1, 1)); | |
