How to stop setInterval in react when navigating between pages using NavLink?

Question

React

React application, the setInterval function works on the page.

import React from "react";
import logo from "./logo/logo.svg";
import style from "./StartPage.module.css";
import Cell from "./Cell";
import { NavLink } from "react-router-dom";

export const change = (arr) => {
  let i = -1;
  setInterval(function () {
    document.querySelector("i").className =
      arr[(i = ++i == arr.length ? 0 : i)];
  }, 1000);
};

const StartPage = () => {
  const arrD = [style.indicator, style.indicatorleft];
  change(arrD);
  return (
    <div className={style.grid}>
      <img src={logo} alt="bugaga"></img>

      <div className={style.radiobutton}>
        <NavLink
          onClick={() => {
            clearInterval(change);
          }}
          to="/radio">
          RadioButton
        </NavLink>
        <div className={style.list}>
          <div className={style.cell}>
            <div className={style.togle}>
              <i className={style.indicatorleft}></i>
            </div>
          </div>
          <Cell />
          <Cell />
          <Cell />
          <Cell />
          <Cell />
          <Cell />
          <Cell />
          <Cell />
        </div>
      </div>
      <div className={style.radio}>
        <NavLink to="/button">Button</NavLink>
        <div className={style.list}></div>
      </div>
    </div>
  );
};

export default StartPage;

But when going to another page through NavLink

<div className={style.radiobutton}>
        <NavLink
          onClick={() => {
            clearInterval(change);
          }}
          to="/radio">
          RadioButton
        </NavLink>

Gives an error message.
Tell me how to fix it or another correct way to stop setInterval when NavLink fires.
If you need code for other components, write

Answer 1

document.querySelector("i").className =
      arr[(i = ++i == arr.length ? 0 : i)];

the error occurs because you are trying to set the className as an array.
the correct entry is className = "myClass" or something similar. What would you like to do with this code? just disable the timer?
