Tell us what’s happening:

emptystring: (quotes) => quotes

Don;t know what I’m doing wrong

Your code so far

<!-- file: index.html -->


/* file: script.js */
// User Editable Region

const spreadsheetFunctions = {
  
  sum,
  average,
  median,
  even: nums => nums.filter(isEven),
  someeven: nums => nums.some(isEven),
  everyeven: nums => nums.every(isEven),
  firsttwo: nums => nums.slice(0, 2),
  lasttwo: nums => nums.slice(-2),
  has2: nums => nums.includes(2),
  increment: nums => nums.map(num => num + 1),
  random: ([x, y]) => Math.floor(Math.random() * y + x),
  range: nums => range(...nums),
  nodupes: nums => [...new Set(nums).values()],
  emptystring:  (quotes = "") => quotes 
  
}

Happy coding
