如何在收益率上修复“未捕获的SyntaxError：意外标识符”

Question

我想在遍历数组以调用API函数时使用生成器函数。

我尝试使用setTimeout，但是功能没有暂停。它进行了2500次调用，并导致CORS提取API错误。

function* subjectGenerator(){
    subjects.forEach(subject=>{
        let examyear =  startYear; 
        while (examyear <= endYear) {
            const api = createQuestionsURLApi(subject, examyear);
            // this.subject = subject.toLowerCase();
            getQuestionFromURL(api, subject);
            console.log(subject, api);
            yield examyear++;
        }

    });
}

我希望收益能够被接受，所以我可以使用subjectGenerator.next（）进行循环。

感谢@briosheje

function* subjectGenerator(){
    for(let i = 0; i < subjects.length; i++){
        const subject = subjects[i];
        let examyear =  startYear; 
        while (examyear <= endYear) {
            const api = createQuestionsURLApi(subject, examyear);
            getQuestionFromURL(api, subject);
            console.log(subject, api);
            yield examyear++;
        }
    }
}
