Array

Array nodes operate on ordered collections of values. They cover the full range of collection operations — accessing elements, transforming collections, searching, grouping, and building new arrays.

All Array nodes are pure (blue header, no execution pins). For iterating over arrays with side effects, use the For Each flow control node instead.

---

Array Length

Get the number of elements in an array.

Pure. Use Array Length to check if a collection is empty or to determine loop bounds.

---

Array Get

Get an element by index (zero-based).

Pure. Use Array Get to access specific positions — the first result, a known offset, or a computed index.

---

Array First

Get the first element of an array.

Pure. Use Array First to get the top result from a sorted or filtered collection.

---

Array Last

Get the last element of an array.

Pure. Use Array Last to get the most recent entry in a chronological list.

---

Array Push

Append an item to the end of an array. Returns a new array.

Pure. Use Array Push to build arrays incrementally — collecting results, adding to a list.

---

Array Concat

Combine two arrays into one.

Pure. Use Array Concat to merge results from multiple sources into a single collection.

---

Array Slice

Extract a sub-array by start and end indices.

Pure. Use Array Slice to take the first N elements, skip elements, or extract a window.

---

Array Contains

Check if an item exists in the array.

Pure. Use Array Contains to check membership — is an IP in the blocklist, is a user in the allowed group.

---

Array Index Of

Find the index of an item in the array. Returns -1 if not found.

Pure. Use Array Index Of to locate a specific element for subsequent operations.

---

Array Reverse

Reverse the order of elements in an array.

Pure. Use Array Reverse to flip chronological order, process items from newest to oldest.

---

Array Sort

Sort an array by value or by a key within each element.

Pure. Use Array Sort to rank results — sort alerts by severity, users by name, or events by timestamp.

---

Array Filter

Keep only elements that match an expression.

Properties:

• Expression — the filter expression using item as the current element (default: item != null).

Pure. Use Array Filter to narrow down results — keep only high-severity alerts, active users, or non-null values.

---

Array Map

Transform each element using an expression.

Properties:

• Expression — the transformation using item as the current element (default: item).

Pure. Use Array Map to extract a single field from each object, format values, or reshape data.

---

Array Reduce

Fold an array down to a single value using an accumulator expression.

Properties:

• Expression — the reduction using accumulator and item (default: accumulator + item).

Pure. Use Array Reduce to sum values, build concatenated strings, or merge objects from a collection.

---

Array Find

Find the first element that matches an expression.

Properties:

• Expression — the search condition using item (default: item != null).

Pure. Use Array Find to locate a specific entry — the alert with a matching ID, the first failed check.

---

Array Find Index

Find the index of the first element that matches an expression.

Properties:

• Expression — the search condition using item (default: item != null).

Pure. Use Array Find Index when you need the position rather than the element itself.

---

Array Every

Check if all elements in an array match an expression.

Properties:

• Expression — the condition to test using item (default: item != null).

Pure. Use Array Every to validate that all entries meet a requirement — all checks passed, all users confirmed.

---

Array Some

Check if any element in an array matches an expression.

Properties:

• Expression — the condition to test using item (default: item != null).

Pure. Use Array Some to check for the presence of a condition — any alert is critical, any IP is blocklisted.

---

Array Distinct

Remove duplicate elements from an array.

Pure. Use Array Distinct to clean up collections — unique IP addresses, deduplicated user lists.

---

Array Flatten

Flatten nested arrays to a specified depth.

Pure. Use Array Flatten to merge nested results into a single list — combining paginated API responses.

---

Array Group By

Group array elements into an object by a shared key value.

Pure. Use Array Group By to organize data — group alerts by severity, events by source, or users by role.

---

Array Zip

Pair elements from two arrays into an array of two-element arrays.

Pure. Use Array Zip to combine parallel data — pairing IP addresses with their reputation scores.

---

Make Array

Create an array from individual element inputs.

Pure. Use Make Array to construct small arrays from separate values without writing JSON.
