Guidelines for converting an array into checkboxes using React Native with TypeScript

As I embark on my React Native journey, I have chosen to use TypeScript in my project. Currently, I am faced with the challenge of mapping an array into a checkbox. Enclosed below is a snippet from my JSON file:

{ 
   "stud_name": "Adam",
   "sex": "male",
   "attendance": false,
   "eligibility": false
}

I am looking for guidance on how to integrate attendance and eligibility into the checkboxes within my React Native code. The following excerpt showcases the checkbox implementation:

export const StudentRegisterExam: React.FC<Props> = ({}) => {
  const StudentData = useContext(StudentStoreContext);

  const firstRender = useRef(true);
  useEffect(() => {
    if (firstRender.current) {
      firstRender.current = false;
      return;
    }
    if (response !== undefined) {
      if (response.status === 201 || response.status === 200) {
        StudentData.details = {
           name: response.data.name,
           sex: response.data.sex,
           eligibility: response.data.eligibility,
           attendance: response.data.attendance
       };
     }
   }
 }, [response]);

return (
      <View>
        <Text>{StudentData.response.name}</Text>
        <Text>{StudentData.response.sex}</Text>
        <CheckBox /> <- How can I incorporate {StudentData.response.eligibility} into this checkbox?
        <CheckBox />
      </View>
 );

Your assistance is greatly appreciated. To manage the StudentData, I have established a file named StudentStore.ts within my store folder.

I'm having trouble understanding your point. When we map an array, we iterate over each of its values. Are you asking how to pass the data into your component?

The real question is, what does your checkbox component look like? It would be helpful if you could share the source code with us... or are you using a UI library like react-elements.

If you're using react-elements Checkbox, here's an example:

const { response } = StudentData;
return (
      { Object.keys(response).map(item =>
      <View>
        <Text>{response[item].stud_name}</Text>
        <Text>{response[item].sex}</Text> 
        <CheckBox
          center
          title='{response[item].stud_name}'
         checked={response[item].eligibility}
        />

      </View>
      ) }
 );

I hope this helps clarify things for you.

It seems like you were looking for information on how to loop through JSX code, correct? Or maybe you wanted to know how to pass parameters into a component?

You can execute loops within {}, but you can only use expressions there... traditional if, for, and while loops won't work. Instead, try method calls like yourArr.forEach, yourArr.map, or ternary operators as alternatives for if conditions.
