💻 Code

entries<T>(o: { [s: string]: T } | ArrayLike<T>): [string, T][];

declare function normalize(p: string): string

export function handlePackageBins<K extends string>(bins: Record<K, string>)
{
	return Object.entries(bins)
		.reduce((a, [k, bin]) =>
		{
			normalize(bin)
            a[k] = bin
			return a
		}, {} as Record<K, string>)
}

🙁 Actual behavior
