Export a function: can't find variable

I try to create a function and export it to be called in differents components but i don't know very well how it work and an error occur when I do this:

function code:

export function myFunction( param ) {
   //my code...
   var ret = param
   return ret;
};

Call in the component:

import {components} from 'react'
import {myFunction} from './class.js';
import {Alert} from 'react-native';

class myClass extends Component{
  componentDidMount() {
    var val = myFunction('the param');
    Alert.alert(val);
  }
}

And occur this error:

Can't find variable: myFunction

Thanks for help.

you are doing it wrong. Here is the right way to do it. Use const instead of function. And also, you can always use arrow function as below:

export const myFunction = ( param ) => {
  //my code...
  var ret = param
  return ret;
};

Now you can import myFunction as you did above. Hope it helps.
