Errors:

The tag <ICONCAR> is unrecognized in this browser. If you meant to render a React component, start its name with an uppercase letter

The tag <ICONHOME> is unrecognized in this browser. If you meant to render a React component, start its name with an uppercase letter.

i am getting the above error

if <ICONHOME></ICONHOME> or <ICONCAR></ICONCAR> works instead of <IconComponent ></IconComponent>

Answer

You need to do a mapping between sring and react component. Even tough the names may be equals it has to be done.

Here is an example:

import { ICONCAR, ICONHOME }  from "/icons/MyIcons";

const iconMapping: Record<string, () => JSX.Element> = {
  "ICONCAR": ICONCAR,
  "ICONHOME": ICONHOME
};

export const TestScreen() => {
     useEffect(() => {
        
    }, []);

    return 
    ( 
    <>
    <div>Title</div>
      {response.data.map((x, index) => {
        const IconComponent = iconMapping[x.iconName];
        if (IconComponent === undefined) {
          //handle it by assigning it to an icon
        }
          return (
            <div>
            <p>Test</p>
            <IconComponent ></IconComponent>
            </div>
            );
       })} 
    </>
    )

}
