Modifying the structure, content, or style of a web page using JavaScript to create dynamic and interactive user experiences.
JavaScript Object Notation, a lightweight data interchange format commonly used for transmitting data between a server and a web application.
Implementing mechanisms to catch and handle errors that may occur during Ajax requests, ensuring graceful degradation and user-friendly error messages.
Addressing security vulnerabilities such as cross-site scripting (XSS) and cross-site request forgery (CSRF) when implementing Ajax functionality.
A mechanism that allows resources on a web page to be requested from another domain, enabling cross-domain Ajax requests while maintaining security.
Pre-built JavaScript libraries such as jQuery, Prototype, and Axios that provide simplified APIs and utilities for Ajax programming.
Following established guidelines and conventions to write clean, efficient, and maintainable Ajax code, improving code quality and developer productivity.
An HTTP request method used to retrieve data from a server in Ajax applications.
An HTTP request method used to send data to a server for processing in Ajax applications.
An HTTP request method used to update existing data on a server in Ajax applications.
An HTTP request method used to delete data from a server in Ajax applications.
Processing and manipulating the server's response to an Ajax request, extracting relevant data and updating the web page accordingly.
Functions passed as arguments to other functions, allowing them to be executed asynchronously or after a certain event occurs in Ajax programming.
An abstraction that represents the eventual completion or failure of an asynchronous operation, simplifying error handling and asynchronous code flow in Ajax programming.
Storing and reusing previously fetched data in Ajax applications to reduce server load and improve performance.
Managing multiple Ajax requests simultaneously, ensuring proper synchronization and avoiding race conditions in web applications.
Visual feedback to inform users about the progress of an Ajax request, improving user experience and perceived performance.
Making Ajax requests to a different domain than the one hosting the web page, requiring special handling due to security restrictions.
Converting complex data structures into a format suitable for transmission in Ajax applications, such as converting JavaScript objects to JSON strings.
Verifying the identity of users or applications accessing Ajax resources, ensuring secure access to protected data and functionality.
Granting or denying access to Ajax resources based on the permissions and privileges of the authenticated user or application.
A security vulnerability where malicious scripts are injected into web pages viewed by other users, potentially compromising their data or executing unauthorized actions.
A security vulnerability where an attacker tricks a user into performing unwanted actions on a web application in which they are authenticated.
Web applications that dynamically update the content of a single web page, providing a more fluid and responsive user experience using Ajax techniques.
Generating the initial HTML content on the server and sending it to the client, improving performance and search engine optimization for Ajax-powered websites.
APIs provided by web applications to expose their functionality and data, allowing other applications to interact with them using Ajax requests.
A mechanism that allows resources on a web page to be requested from another domain, enabling cross-domain Ajax requests while maintaining security.
A security policy enforced by web browsers that restricts web pages from making requests to a different domain than the one hosting the page, preventing cross-site scripting attacks.
An HTTP OPTIONS request sent by the browser to the server before making a cross-origin Ajax request, checking if the server allows the actual request.
HTTP headers sent by the server to indicate which origins are allowed to access its resources, controlling cross-origin Ajax requests.
An HTTP response header that specifies which origins are allowed to access the server's resources in cross-origin Ajax requests.
An HTTP response header that specifies the HTTP methods allowed for cross-origin Ajax requests to the server's resources.
An HTTP response header that specifies the HTTP headers allowed for cross-origin Ajax requests to the server's resources.
An HTTP response header that indicates whether the server allows cross-origin Ajax requests to include credentials such as cookies or HTTP authentication.
An HTTP response header that specifies the maximum time, in seconds, that the browser can cache the CORS-related information for a particular resource.
An HTTP response header that lists the headers that can be exposed to the client in cross-origin Ajax requests.
A security vulnerability where an attacker includes malicious scripts from a different domain into a web page, potentially compromising user data or executing unauthorized actions.
A security vulnerability where an attacker hijacks a WebSocket connection between a client and a server, potentially intercepting or modifying the data exchanged.
Techniques and best practices to prevent cross-site script inclusion vulnerabilities, such as validating and sanitizing user input and using content security policies.
Techniques and best practices to prevent cross-site WebSocket hijacking vulnerabilities, such as using secure WebSocket connections and implementing proper authentication and authorization mechanisms.
Designing web applications to provide a basic level of functionality even if certain features or technologies, such as Ajax, are not supported or disabled in the user's browser.
Designing web applications to provide a baseline experience for all users, and then enhancing it with additional features and technologies, such as Ajax, for users with modern browsers.
Writing JavaScript code that does not interfere with the normal functioning of a web page, allowing it to degrade gracefully and be accessible to users with disabled or unsupported JavaScript.
The process of removing unnecessary characters, such as whitespace and comments, from JavaScript code to reduce its size and improve loading times in Ajax applications.
The process of transforming JavaScript code into a form that is difficult to understand or reverse-engineer, protecting intellectual property and preventing unauthorized modifications.
Capturing and logging errors that occur during Ajax requests, helping developers identify and fix issues to improve the reliability and stability of web applications.
Techniques and strategies to improve the speed and efficiency of Ajax applications, such as minimizing network requests, optimizing code, and caching data.
Ensuring that Ajax functionality works correctly across different web browsers and versions, providing a consistent user experience for all users.
Designing Ajax-powered web applications to be responsive and optimized for mobile devices, providing a seamless user experience on smartphones and tablets.
Designing Ajax applications to be accessible to users with disabilities, following web accessibility guidelines and providing alternative ways to access content and functionality.
Designing Ajax applications to support multiple languages and cultures, allowing users from different regions to use the application in their preferred language.
Adapting Ajax applications to specific languages, cultures, and regions, including translating text, formatting dates and numbers, and adjusting content for local customs and preferences.
