How can I delete subjectname from JSON data my code is here http://localhost:3003/CourseList is my local JSON server

 const deleteSub = async id => {
        try{
          const data = await axios.get("http://localhost:3003/CourseList")
          //How should I map and delete the subname ???? 
        }
        catch(err){
          console.log(err.message)
        }
      };

Have you tried looping the json with `.forEach` and using `delete` keyword to delete the key you want ? — Nisanth Reddy, May 13 '21 at 10:44
What JSON? Please may you include all the relevant code _in the question itself_ making sure it is a [mcve]? — evolutionxbox, May 13 '21 at 10:50

You can use .filter method to do this

const deleteSub = async id => {
        try{
          const data = await axios.get("http://localhost:3003/CourseList")
          const filteredData = data.filter(d => d.id !== id)
          console.log(filteredData)
        }
        catch(err){
          console.log(err.message)
        }
};

Hi, seems like OP's question was to delete a particular key rather than filter entire objects. – Nisanth Reddy May 13 '21 at 10:50
