Is there a way to add an active class onClick for an array of buttons?

Question

I map through the buttons array and get three buttons. What i want to achieve is to be able to identify which button is clicked and add an active class

import React from "react";
import { useState } from "react";
import style from "./years.module.scss";

const Years = props => {
 const [activeClass, setActiveClass] = useState(null);
 const buttons = ["year one", "year two", "year three"];



return (
 <div className={style.box}>
   {buttons.map((button, index) => {
       console.log(index,button)
     return (
       <button key={index} className={`${style.btn} ${style.active}`} >
         {button}
        </button>
     );
   })}
</div>
);
};

export default Years;

I use css modules to style the buttons

Answer 1

Just connect handler with each button - if clicked, the state is changed and stores the index of active button. If it's active - add class.

const changeActiveButton = (i) => () => {
   setActiveClass(i);
};

<button 
   onClick={changeActiveButton (index)}
   className={`${style.btn} ${index === activeClass ? style.active : ''}`}

Answer 2

<button key={index} className={`${style.btn} ${style.active}`} onClick={()=>setActiveClass(button)} >
  {button}
</button>
