@lang:zip

Combine two arrays element-wise into an array of pairs.

On-chain (@lang:zip!): Either or both sides may be live, a length mismatch reverts, and the result is a flat word-pair payload, so @len! counts words rather than pairs.

Returns: array

Syntax

@lang:zip(a b)

Arguments

Name	Type	Description
a	array	First array to zip
b	array	Second array to zip

• @unzip — split pairs into two arrays
• @enumerate — pair elements with indices

On-chain face (@zip!)

Interleave two word payloads on-chain through zipWords. Either side, or both, may be live (a call or nested face) or a constant array literal. When both are live the second offset is computed on-chain from the first payload's length. A word-count mismatch reverts with WordCountMismatch.

Examples

load lang

set $amm 0x44fA8E6f47987339850636F88629646662444217

assert @zip!($amm::{caps()(uint256[])} [7 8]) == 0x1122
