--- id: 5cdafbb0291309899753167f title: Create a JavaScript Promise challengeType: 1 forumTopicId: 301197 dashedName: create-a-javascript-promise --- # --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: ```js 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`. ```js assert(makeServerRequest instanceof Promise); ``` Your promise should receive a function with `resolve` and `reject` as parameters. ```js 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-- ```js ``` # --solutions-- ```js const makeServerRequest = new Promise((resolve, reject) => { }); ```
