--description--
A promise in JavaScript is exactly what it sounds like - you use it to make a promise to do something, usually asynchronously. When the task completes, you either fulfill your promise or fail to do so. Promise is a constructor function, so you need to use the new keyword to create one. It takes a function, as its argument, with two parameters - resolve and reject. These are methods used to determine the outcome of the promise. The syntax looks like this:
const myPromise = new Promise((resolve, reject) => {
});
--instructions--
Create a new promise called makeServerRequest. Pass in a function with resolve and reject parameters to the constructor.
--hints--
You should assign a promise to a declared variable named makeServerRequest.
assert(makeServerRequest instanceof Promise);
Your promise should receive a function with resolve and reject as parameters.
assert(
code.match(
/Promise\(\s*(function\s*\(\s*resolve\s*,\s*reject\s*\)\s*{|\(\s*resolve\s*,\s*reject\s*\)\s*=>\s*{)[^}]*}/g
)
);

const makeServerRequest = new Promise((resolve, reject) => {
});
