src/utils/array.ts:21–23

(array: T[], addition: Iterable<T> | ArrayLike<T>)

// NOTE: Pushing items like `arr.push(...items)` is 3x slower in Firefox

export function push<T>(array: T[], addition: Iterable<T> | ArrayLike<T>): void {
    forEach(addition, (a) => array.push(a));
}

// NOTE: Using `Array.from()` is 2x (FF) — 5x (Chrome) slower for ArrayLike (not for Iterable)
