You are right, but I don't want that value of codemirror to be store on state

@pawan-poudel-github you want to use ref?

Yes I am saying something like of actual codemirror like EditorRef.current.setValue("int a =5")

import React, { useRef, useState } from "react";
import CodeMirror from "@uiw/react-codemirror";
import { javascript } from "@codemirror/lang-javascript";

export default function App() {
  const $edit = useRef();
  const [val, setVal] = useState("console.log('hello world!');");
  const onChange = React.useCallback((value, viewUpdate) => {
    console.log("value:", value);
  }, []);
  const onRefChange = () => {
    $edit.current.view.dispatch({
      changes: { from: 0, to: 12, insert: "test" + new Date() }
    });
  };
  return (
    <div>
      <button onClick={() => setVal("Time: " + new Date())}>
        Change Value
      </button>
      <button onClick={onRefChange}>Ref Change Value</button>
      <CodeMirror
        value={val}
        ref={$edit}
        height="200px"
        theme="dark"
        extensions={[javascript({ jsx: true })]}
        onChange={onChange}
      />
    </div>
  );
