javascript - 将数组中的唯一值添加到另一个 JS

Question

假设我有一个这样的对象数组：

let arrayOfObjects = [{Name: "A", Number: "1"} {Name: "A", Number: "2"} {Name: "B", Number: "2"} {Name: "A", Number: "2"}]

我怎样才能遍历它，并将“Number”的唯一值添加到新数组中？所以所需的新数组将是：

let newArray: [1,2]

let newArray = [...new Set(arrayOfObjects.map(el => parseInt(el.Number)))]
