how to use java script regular expression?

010-****-1234. I want to express it in a regular expression. It's so hard to express.

this is my code

const handlePhone = (e) => {
    const value =
 phoneRef.current.value.replace(/\d(?=\d{4})/g, "*");
    const numberLength = 
11;

    let result;
    result = "";  
    for (let i = 0; i < value.length && i < numberLength; i++) {
      switch (i) {
        case 3:
          result += "";
          break;
        case 7:
          result += "";
          break;

        default:
          break;
      }
      result += value[i];
    }
     phoneRef.current.value = result;

    setNum(e.target.value); 
  };
