Asynchronous programming is often intimidating, it's not how we normally consider writing code. This course shows how promises and async/await can help simplify async programming.

Asynchronous programming is often confusing when first learning JavaScript. In this course, Asynchronous Programming in JavaScript,, you’ll gain the ability to handle async programming in JavaScript. First, you’ll explore consuming promises. Next, you’ll discover creating your own promises. Finally, you’ll learn how to use async/await to handle asynchronous programming. When you’re finished with this course, you’ll have the skills and knowledge of JavaScript promises needed to handle asynchronous code.

Career center

Learners who complete Asynchronous Programming in JavaScript will develop knowledge and skills that may be useful to these careers:
JavaScript Developer
Also known as JavaScript Engineer, a JavaScript Developer specializes in writing and maintaining JavaScript, a high-level programming language that makes web pages interactive and is the foundation for virtually all modern web apps and websites. Because asynchronous programming is a core aspect of JavaScript, the course, Asynchronous Programming in JavaScript, can be an important resource for someone who wants to work as a JavaScript Developer. The course may help build a foundation for the concepts and skills needed to succeed in this career.
Web Developer
A Web Developer is one who specializes in developing websites and web applications, typically from scratch. Asynchronous coding is important as it helps web pages load quickly and appear responsive to users. The course, Asynchronous Programming in JavaScript, may be useful to someone who wants to work as a Web Developer, as it can help establish a foundation for how to handle asynchronous programming.
Node.js Developer
Node.js is a Javascript runtime environment used on the back-end of websites and applications. Asynchronous programming is particularly useful in Node.js, as it helps Node.js Developers create fast and efficient applications and services. The course, Asynchronous Programming in JavaScript, may help build a foundation for understanding how to write asynchronous code with Node.js, which can be beneficial for someone looking to work as a Node.js Developer.
React Developer
React is a JavaScript library for building user interfaces and front-end web development. Asynchronous programming is important for React, as it helps React Developers create complex, interactive, and responsive user interfaces. The course, Asynchronous Programming in JavaScript, may help build a foundation for understanding how to write asynchronous code with React, which can be beneficial for someone looking to work as a React Developer.
Software Developer
A Software Developer performs the tasks of designing, developing, and testing software or other applications. Because nearly all modern software is user-facing, almost all Software Developers need to have knowledge of how to write front-end and back-end code. Asynchronous code is critical to making this handoff as fast and seamless as possible. The course, Asynchronous Programming in JavaScript, can help build a foundation for understanding how to write asynchronous code, making it a useful course for some Software Developers.
Software Engineer
Somewhat similar to Software Developers, Software Engineers may have more of a focus on research and development (R & D), rather than only having a focus on writing code. Asynchronous programming may be a particular interest of some Software Engineers whose specialty is in user-facing software. The course, Asynchronous Programming in JavaScript, may be useful for Software Engineers who want to learn more about asynchronous programming, especially if their work involves JavaScript.
Full-Stack Developer
A Full-Stack Developer is similar to a Front-End Developer, but also has knowledge of what is going on in the 'back-end' of a website. The back-end of a website is what users do not engage with directly, such as databases and servers. Asynchronous coding is important for making the transition between back-end and front-end data transfer as seamless as possible. The course, Asynchronous Programming in JavaScript, may be useful to someone who wants to work as a Full-Stack Developer. It can help establish a foundation for understanding how to handle asynchronous programming, which will be an important skill to have as a Full-Stack Developer.
Front-End Developer
A Front-End Developer is one who specializes in those parts of a website that users see and engage with. They need a strong understanding of how to use code to make web pages interactive and user-friendly, such as how to make drop-down menus, add event listeners for images and other items, and so on. The course, Asynchronous Programming in JavaScript, may be useful for someone who wants to get into this career because it helps build a foundation and understanding for how to write asynchronous code. Asynchronous code is the backbone of user-friendly web interactions such as hover effects and button clicks, so it is a good skill to have for any aspiring Front-End Developer.
