具有收益返回的静态生成器函数的正确打字稿语法是什么？

Question

I am trying to write a static function on a class, which uses the generator/yield pattern. Can somebody give me a code example of what the method signature syntax looks like? Specifically, I am trying to write a fibonacci generator, but any number generator will do.

class Mathy {
    static yieldFibonacci(maxValue: number = Number.POSITIVE_INFINITY): IterableIterator<number> {
        let current = 0
        let next = 1
        while (next < maxValue) {
            yield next
            [(current, next)] = [next, current + next]
        }
    }
}

Answer 1

class Mathy {
    static *yieldFibonacci(maxValue: number = Number.POSITIVE_INFINITY): IterableIterator<number> {
        let current = 0
        let next = 1
        while (next < maxValue) {
            yield next
            ;[current, next] = [next, current + next]
        }
    }
}
