Tests:
Flatmap
Array.from(new Set(productData.masters.flatMap((master) => master.variants.flatMap((size) => size.size))));
Reduce
Array.from(new Set( productData.masters.reduce((acc, master) => { const sizes = master.variants.reduce((variantAcc, variant) => { return [...variantAcc, variant.size]; }, []); return [...acc, ...sizes]; }, []), ))
