Code challenge doesn't accept my code

Hi guys, I wrote this code:

days.forEach(day => {

  let character2 = `${day.charAt(0)}${day.charAt(1)}`;
  dayAbbreviations.push(character2);

});

however, the program says illegal character. What should I do?

app.js 
const days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
let dayAbbreviations = [];

// dayAbbreviations should be: ['Su', 'Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa']
// Write your code below

days.forEach(day => {

  let character2 = `${day.charAt(0)}${day.charAt(1)}`;
  dayAbbreviations.push(character2);

});

Where is the error? It worked just fine here in Visual Code. [ 'Su', 'Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa' ]

PS: Another way you could do it is using map, like the following: dayAbbreviations = days.map(day => day.slice(0,2));

Try using "substring" instead. That is: let character2 = day.substring(0, 2). Substring extracts the characters from a string between two specified indices.

Many thanks for your answers. I used split method and it works, but my code is correct. My only question is why the first version is wrong in code challenge and good in workspace

Hi, i think the problem is that you use Jquery. i think the courses and practice is mostly in vanilla js try to rewrite you code into vanilla js and i think is should work fine.

Thanks Ivan, but I don't think it's Jquery. I use template literals and the code runs in workspace but here in the code challenge part doesn't work.
