Set

A Set-typed variable holds the JS Set collection — a list of values with duplicates automatically removed. The default-value text you type into the Variables panel must be a JSON array, e.g. ["a","b","c"]; typing anything that isn't a valid JSON array (a bare string, a number, an object) is rejected with a clear message.

Compiles to​

let tags = new Set(["a", "b", "c"]);

The array you typed is passed straight into new Set(...), which de-duplicates its elements at runtime exactly like any hand-written JS Set — so typing ["a","a","b"] still produces a Set containing only "a" and "b".

Leaving the default-value field empty still compiles to a real, constructed Set — new Set() — rather than leaving the variable undeclared.

Get Variable / Set Variable​

A Get tags node reads it back; a Set tags node assigns a new value and continues:

Get Variable

Set Variable

The Set node's "Value" pin takes the same JSON-array text as the default-value field — an unwired literal there is wrapped in new Set(...) the exact same way.

Use case​

  • Unique tags/roles: A collection of tags, permission names, or category labels where duplicates should never be possible — adding the same tag twice has no effect, without you having to check for it yourself.
