how to declare demands ?

Hello, i'm really confused about how to declare demands, in the documentation it states that there is a from-to locations pair of values, and in this example i see 3 values inside a single array, i'm confused which one is which:

var vrpSolverOpts = { numNodes: 3, costs: [[0, 10, 10], [10, 0, 10], [10, 10, 0]], durations: [[0, 2, 2], [2, 0, 2], [2, 2, 0]], timeWindows: [[0, 9], [2, 3], [2, 3]], demands: [[0, 0, 0], [1, 1, 1], [1, 1, 1]] };

Let's say i have 3 vehicles with capacity of 15 each.
All goods are loaded from the depot.
and 5 locations to deliver to with the following demands :
location A demands 5
location B demands 3
location C demands 2
location D demands 7
location E demands 10

How can I specify the demands in such case ?
Thank you.

ドキュメントの需要の説明と vrpSolverOpts の例から始め、特にその demands 配列を確認します。各値がロケーションにどのように対応するかを明確にし、issue に記載されている5つの配送先と車両容量について、具体的な例を追加します。
