AJAX programming language lets websites run asynchronous requests. With asynchronous requests, a series of queries run separately from the flow of the main program. Learning AJAX is an intermediate skill for programmers, so taking a course like Intro to AJAX from the Udacity Catalog is a convenient way to get started. An example of what AJAX is used for is an app that lets people search a variety of information sources about a single location, and you get the chance to build an app like that in the Udacity course.

AJAX and Web Server Interaction
The asynchronous nature of AJAX lets you know that the web server doesn't freeze up when a client, which means a web browser, requests new data. The asynchronous functionality allows the user to keep navigating around the web page or pages, and the new data loads without disturbing the current web page that someone's using. When you've mastered AJAX, if you want to continue in the field and earn certification as a developer, Udacity's Front-End Web Developer Nanodegree program is the next step.
The Front-End Web Developer Nanodegree program is offered in cooperation with AT&T, Google, and GitHub. It's set up as four-month course, so you can reach your goal of becoming a web developer in a fairly short time. According to the Bureau of Labor Statistics, web developers make an average of $32.69 per hour or about $68,000 per year. The field is growing much faster than average with a growth rate of 15 percent between 2016 and 2026, and it's suited to people who want to work for themselves and those who want to find positions developing websites for different companies.
