Task 104

Implement the function createSamples that takes a string and returns two samples of it, one in the lowercase
and another one in the uppercase.
#helper.js
const toLowerCase = (s) => {
return s.toLowerCase();
}

const toUpperCase = (s) => {
return s.toUpperCase();
}

export const createSamples = (s) => {
return s;
}

#solution.js
import { createSamples } from './helper.js';

console.log(createSamples('binGO')); // bingoBINGO
console.log(createSamples('R2D2')); // r2d2R2D2

what errors do I need to fix here?

You must use functions toLowerCase and toUpperCase from the file helper.js

And in fact, you're using built-in string functions.

Fix the issue by calling the right functions toLowerCase and toUpperCase from helper.js

I totally forgot about concatenation. The problem is solved now by using following command:

export const createSamples = (s) => {
  return toLowerCase(s) + toUpperCase(s);
}
