is not a function error React?

Hey guys,

I keep getting a is not a function error after I submit my form with or without filling out the the form. I would like to pass my form data (genData,edData,paData) to my Results component. Any help in solving this?

 const [educationData, setEdData] = React.useState([{
    schoolName: "",
    degree: "",
    gradDate: ""

Initially educationData is Array and you have used map method to generate input fields .

The error is caused by the handleSubmit function.
when submit button is clicked educationData is no more an Array but on Object hence is not a function

function handleSubmit(event) {

  // .....
 setEdData(() => {
      return {
        schoolName: "",
        degree: "",
        gradDate: ""

  // ......


{ (input, index) => {  } )

paData will cause the same error too.


props here is an object and Objects are not valid as a React child

  <div className='resultsContainer'>
         {props }

Yes, thank you. As I am working on the issue I also ran into the errors you mentioned. I will update when I have solved the issue.

So, I changed my setEdData and setPaData to be an array in my handleSubmit function but I’m not sure how to get my results to display in my results component. Right now I’m only seeing the genData in the results when I console.log.

take a look at line 3.


since results can have single state, it picks the first one which is genData and ignores rest.

instead of doing that you can use an array or object for convenience

basic: genData,
academic: educationData,
experience: paData
