If you’ve ever needed to count the number of items in an array and weren’t quite sure how to do it, the solution lies with Code by Zapier. And it’s easy to do!

The Setup



let Set = inputData.Set.split(","); // creates array by splitting Input Data Variable at commas

let SetCount = Set.length; // determines the length of the array (aka number of array items)

output = [{SetCount, Set}];


The Results

Dude! I just used this 🙂 The API I’m getting data from has a field that shows everyone who liked something, but doesn’t provide the number. I used this code and it worked like a charm!
