Functional Programming: Learn About Functional Programming

Tell us what’s happening:
There appears to be an error with this challenge, from what I can see i have entered the correct answer, but the FCC console displays this message,

‘TypeError: Cannot read property ‘presets’ of undefined’

and the code has to be reset to remove it. I have copied the correct code in directly from the FCC help section and the same error code appears.

Your code so far

// Function that returns a string representing a cup of green tea
const prepareTea = () => 'greenTea';

Given a function (representing the tea type) and number of cups needed, the
following function returns an array of strings (each representing a cup of
a specific type of tea).
const getTea = (numOfCups) => {
const teaCups = [];

for(let cups = 1; cups <= numOfCups; cups += 1) {
  const teaCup = prepareTea();
return teaCups;

// Only change code below this line
const tea4TeamFCC = getTea(40);
// Only change code above this line
