如何在 TypeScript 中将 Set 转换为数组

How can I convert a Set to an Array in TypeScript

提问by thanhpk

How can I convert a Set (eg, {2,4,6}) to an Array [2, 4, 6] in TypeScript without writing a loop explicitly ?

如何在 TypeScript 中将 Set（例如 {2,4,6}）转换为数组 [2, 4, 6] 而不显式编写循环？

I have tried those following ways, all of them work in JavaScript but none of them work on TypeScript

我尝试了以下方法，它们都在 JavaScript 中工作，但没有一个在 TypeScript 上工作

[...set] // ERR: "Type 'Set<{}>' is not an array type" in typescript

Array.from(set) // ERR: Property 'from' does not exist on type 'ArrayConstructor'
