Learn Functional Programming by Building a Spreadsheet - Step 101

Tell us what’s happening:

I’m trying to create the ‘range’ property which is a function that returns the range of ‘nums’ array…

Your code so far

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:(start , end)=>range(start, end) ,
}
