    You want your project be fast, protected, bugs free, with clean and commented code working on you. You need it to be done in reasonable deadlines, with great orientation to details. Then we think in same way. Greetings and welcome to my profile. My name is Anna Kuprina. I am professional PHP developer. Specialize on Wordpress development. Over 6 years experience building websites and web platforms of any complexity. PHP / WordPress / Javascript / jQuery / AJAX / JSON / CSS3 / HTML5 / Bootstrap / MySQL / WooCommerce / PayPal / Facebook API / Twitter API / API development / Facebook Pixel / Stripe and a lot more. 1) Focus on customers' needs. Most freelancers think about income, project specifications and designs. They expect from you everything, so they just can sit and code without any other thoughts. That doesnt work great. Basically it doesnt work at all. My aim is to understand main idea of customer that pushed him to develop web platform. I think about business and personal needs and prefer to compare it with provided project details and convert it into something that will really work for customer. not just become another website. 2) Keep in touch Project given, developer dissapeared and came back with something done and said "according to providing info" but it completely useless or wrong for you and missing your expectations. Sounds familiar? It is not my way. Each funcion, each button, each technology used is important and each question must be asked to prevent development moving to wrong way and save so valuable time of you. 3) Honesty. Most developers try to hide their mistakes, prove that it is your fault and argue on every detail. That's completely wasted time. when both of you got unrespected result and leave relationship with broken heart. It is not win-win situation and I understand this. My approach is to be honest with every situation and discuss it in time instead of waiting once things go to far. So, if you are tired of such situations and want to save time, nerves and money - give me a shout. Remember, that I am the professional who will first try to understand you and only then deliver product and will put all efforts to meet your expectations. Invite me to your project and get free analyze of your project needs and estimation of work required Kind regards, Anna

What is AJAX (Asynchronous JavaScript + XML)?

AJAX (Asynchronous JavaScript + XML) is a group of interrelated client- and server-side development technologies that allows parts of a webpage to be updated without having to reload the entire page—think of sites like YouTube, Google Maps, Gmail, and tabs within Facebook. It changed usability and the speed of web applications with its innovative concept: asynchronously exchanging small amounts of data with the server behind the scenes, without affecting the rest of the page.

AJAX makes features like drop-down menus, predictive text, auto-filled text, and more possible, all without clicking Refresh. What it means for servers is less stress on the network and faster operations. That’s the core benefit of AJAX-enabled sites: overall, they’re more responsive and very efficient on both sides.

How does AJAX work?

AJAX calls are asynchronous, meaning they’re made behind the scenes, independently from each other and the site as a whole. When a browser makes an AJAX call to the server, it isn’t stuck waiting for a response, halting all of the site’s functionality. Instead, the web service on the server will send the data back to the browser once the task is completed, where client-side scripts will process the response and deliver it to the user.

AJAX breakdown

AJAX uses the following technologies:

  • XML or JSON: the text-only format used to transfer data from server to browser script. Developers are increasingly using JSON over XML because of its native JavaScript compatibility.
  • CSS: the language used to style how the data will look onscreen
  • JavaScript: displays the data in the browser and processes user requests/interactions like clicks
  • XMLHttpRequest objects: the keystone of AJAX, they actually retrieve the data with the server behind the scenes. All modern browsers support XMLHttpRequests.

Callbacks vs. Postbacks.

Pre-AJAX, the rules for client calls to the server—basically, anything the browser requests from a database to make a site responsive—were “postbacks,” plus server-side processing. Post-AJAX, the browser can “callback,” requesting small amounts of data directly from the server—all without needing to wait for a postback.

Benefits of AJAX

  • Better speed and performance
  • More responsive, user-friendly websites and applications
  • Ease of development, thanks to JSON, jQuery, and compilers that help to streamline complex JavaScript code
  • Browser- and platform-independent. Also, Microsoft offers the AJAX Control Toolkit integrated into Visual Studio on the ASP.NET platform.
  • Ideally implemented for updating small bits of information within a web application
  • Allows text box autocomplete and predictive text
  • Won’t slow down with limited bandwidth. With AJAX callbacks, the server won’t get overloaded by requests, which would otherwise cause the app to slow down.

AJAX is just one advancements in the front-end development landscape—learn more about front-end web development and how AJAX fits into the client-side technology landscape as a whole.
