--description--
Promise 是异步编程的一种解决方案 - 它在未来的某时会生成一个值。任务完成,分执行成功和执行失败两种情况。Promise
是构造器函数,需要通过 new
关键字来创建。构造器参数是一个函数,该函数有两个参数 - resolve
和 reject
。通过它们来判断 promise 的执行结果。用法如下:
const myPromise = new Promise((resolve, reject) => {
});
--instructions--
创建一个名为 makeServerRequest
的 promise。给构造器函数传入 resolve
和 reject
两个参数。
--hints--
应该给名为 makeServerRequest
的变量指定一个 promise。
assert(makeServerRequest instanceof Promise);
promise 应该接收一个函数做为参数,该函数应该包含 resolve
和 reject
两个参数。
assert(
code.match(
/Promise\(\s*(function\s*\(\s*resolve\s*,\s*reject\s*\)\s*{|\(\s*resolve\s*,\s*reject\s*\)\s*=>\s*{)[^}]*}/g
)
);
--seed--
--seed-contents--
--solutions--
const makeServerRequest = new Promise((resolve, reject) => {
});
