Overcoming Array Filtering Challenges with Map Function on Make.com

Have you ever found yourself in a situation where you need to filter an array based on a key value that starts with a specific string, rather than being exactly equal to it? If so, you're not alone. This is a common challenge faced by many Make.com users.

Understanding the Problem

Let's say we have an array like this:

[ { myKey: abc123 }, { myKey: abc123456 }, { myKey: xyz } ]

Using the map function, we can easily return the first object by specifying the key value as 'abc123'. But what if we want to return the first two objects, both of which start with 'abc123'?

Unfortunately, the map function doesn't allow us to do this directly. But don't worry, there's a workaround.

The Solution

The solution involves using the Iterator and Array Aggregator functions, along with a filter that performs the startsWith comparison.

Here's a step-by-step guide:

Use the Iterator function to go through each element in the array.
For each element, use the startsWith function to check if the key value starts with 'abc123'.
If it does, use the Array Aggregator function to add it to a new array.

By the end of this process, you'll have a new array that contains only the elements you're interested in.

Troubleshooting Tips

If you're having trouble implementing this solution, here are a few tips:

Make sure you're using the correct syntax for the Iterator and Array Aggregator functions.
Check that your filter is correctly identifying the elements that start with 'abc123'.

Conclusion

While the map function is a powerful tool for working with arrays, it has its limitations. However, by combining it with other functions like Iterator and Array Aggregator, you can overcome these limitations and solve complex problems. Happy coding!
