Learn Functional Programming by Building a Spreadsheet - Step 99

Tell us what’s happening:

The error I get is:

Your spreadsheetFunctions object should have a has2 property.

I don’t understand why it doesn’t accept what I typed. I have checked the forum, and from what I have seen from other posts what I typed should be passing.

Your code so far

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

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

const spreadsheetFunctions = {
  sum,
  average,
  median,
  even: nums => nums.filter(isEven),
  firsttwo: nums => nums.slice(0, 2),
  lasttwo: nums => nums.slice(-2),
  has2: nums => nums.includes(2),
  increment: nums.map(num => num + 1)
}

// User Editable Region
/* file: styles.css */

this should have been an arrow function that takes one param nums

That was it, I’ve been staring at this for too long. Thanks for the quick reply
