Expected an assignment or function call and instead saw an expression no-unused-expressions - how to fix this CI error?

Question

Expected an assignment or function call and instead saw an expression no-unused-expressions, I need help on fixing this. Thanks

 export const setDecimalFormat = amount => { ['de', 'fr'].includes(getLocale())? amount.replace(/\./g, ','): amount; };

Answer 1

Try returning the value

If an arrow function is simply returning a single line of code, you can omit the statement brackets and the return keyword. This tells the arrow function to return the statement.

export const setDecimalFormat = amount => {
  return ['de' , 'fr'].includes(getLocale())
    ? amount.replace(/\./g, ',')
    : amount;
};
