Description

Currently, kv.Collection.Every uses kv.Collection.Each to iterate over the collection, which doesn't return early when a non-matching value is encountered, forcing more iterations than necessary.

Contributor guide

Research direction
Examine the current implementation of Every and Each in the go collections package. Understand that Every uses Each internally, which does not support early return. Modify the Every function to iterate directly with a for loop and a boolean flag, returning false as soon as a non matching element is found.
