concat

text →
concat(
    separator: text = ""
) → text

Combines accumulated text values in source order, inserting the separator only between values.

Parameters

Name	Type	Required	Description
separator	text	No	Specifies the text inserted between consecutive accumulated values. Defaults to "".

Argument evaluation

• separator: Evaluated once in the enclosing context before accumulation. The result is reused between accumulated values.

Behavior

The separator defaults to the empty string. Empty input returns empty text. Empty values still participate in separator placement, and accumulating null is invalid.

Examples

{"a", "b", "c"} | concat("-") → "a-b-c"
