Making Asynchronous Calls: Ajax allows you to make asynchronous calls to a web server. This allows the client browser to avoid waiting for all data to arrive before allowing the user to act once more. Increased Speed: The main purpose of Ajax is to improve the speed, performance and usability of a web application.

Here are 20 top-notch websites that cover the subject of Ajax.

• Ajax resource center (developerWorks)
• Mozilla Developer Center (AJAX)
• AJAX Today.
• ajax.solutoire.com.
• SitePoint: JavaScript & Ajax Tutorials.
• Encosia.
• Ajax Technology Center.
• Ajax Blog.

AJAX stands for Asynchronous JavaScript and XML. AJAX is a new technique for creating better, faster, and more interactive web applications with the help of XML, HTML, CSS and Java Script. Conventional web application transmit information to and from the sever using synchronous requests.

Google made AJAX popular. 9. AJAX can work with web application. 10.

Disadvantages of AJAX

• It increases design and development time.
• Complex.
• Less security.
• Search Engines cannot index AJAX pages.
• Browsers which disabled JavaScript cannot use the application.
• Another server cannot display information within the AJAX.

It’s a front-end tool used to communicate with the back-end. All the AJAX related code is written in JavaScript, and the corresponding handler code goes in your server side implementation, which is could be in any language. It is the only way to talk with the server from the browser.

Languages used for the front end are HTML, CSS, JavaScript while those used for the backend include Java, Ruby, Python, . Net.

JSON, or JavaScript Object Notation is used as a means of passing data in a format that is universally recognized. Because there are interfaces available in JavaScript, PHP, Python and other languages, it is neither front-end or back-end.

Python: Is Python front end or back end? The simple answer is yes: Python can be used for either front-end or back-end development. That said, it’s approachable syntax and widespread server-side use makes Python a core programming language for back-end development.

By default, JavaScript is at the first place when it comes to frontend development. Based on the StackOverflow survey (the survey involved by 64,000 developers), it is on the top among both frontend and backend programming languages and stays ahead of Java, Python, PHP, C#, and others.

Front end developers make an average salary of $76,000, and backend developers averaging $75,000. While it’s not the highest salary in the tech industry, you can make a lot more with experience. Front end and backend developers earn hefty salaries.

Python is better than PHP in long term project. PHP has low learning curve, it is easy to get started with PHP. Compare to PHP Python has lower number of Frameworks. Popular ones are DJango, Flask.

Some years ago, Python was faster than PHP, but after the release of PHP 7, this has changed. The core PHP team has done a great deal to speed up the language so now PHP is faster than Python and many other languages. If developers need to process huge amounts of data, high speed may greatly improve performance.

It’s no secret among web developers and programmers in general: PHP doesn’t have the best reputation. While many of the arguments against PHP still stand today, there’s also a bright side: you can write clean and maintainable, fast and reliable applications in PHP. …

In terms of application speed, PHP 7 is faster than Python. Which is easier to learn Python or PHP? In comparison to PHP and other programming languages, Python is a lot easier to read and learn. With relatively simpler coding, Python has a clear, brief and orthogonal syntax.

KEY DIFFERENCE. Python is a high-level object-oriented programming language used for rapid application development whereas PHP stands for Hypertext pre-processor used to develop a dynamic website or web application. Python has a small number of frameworks whereas PHP has many frameworks.

PHP is one of the oldest programming languages used by developers across the world. One reason behind the popularity of PHP is the age of its codebase. The longer the language sticks around, the more legacy code it usually generates.

The C programming language is so popular because it is known as the mother of all programming languages. This language is widely flexible to use memory management. C is the best option for system level programming language.

Overall Python is better than C++ in terms of its simplicity and easy syntax. But C++ is better in terms of performance, speed, vast application areas, etc. C and C++ form the basis of every programming. Python is in fact built on C with web programming in mind.
