BETWEEN — Range Filtering
`BETWEEN a AND b` is inclusive on both ends. Cleaner than `col >= a AND col <= b`. For dates, watch for end-of-day vs midnight boundaries.

range — Lazy Number Iterator
A generator-based numeric range: `[start, end)` with an optional step. Lazy so it doesn't allocate a huge array up front; consume with for…of or Array.from.
JavaScript
Range Generator
Generates an array of numbers from start to end (inclusive) with an optional step. Supports negative steps for counting down. Covers the most common use case of Array.from({ length: n }, (_, i) => i) with a much cleaner API, and handles arbitrary start/end/step combinations.
