What is Incremental Static Regeneration (ISR) in Next.js?
ISR allows updating static pages after they have been deployed. By using the `revalidate` key in `getStaticProps`, you can set a time interval for when Next.js will regenerate the page. Example: A blog post can be statically generated, and ISR will update it at regular intervals if the content changes.

What is XSLT in XML?
XSLT (eXtensible Stylesheet Language Transformations) is a language used to transform XML documents into other formats, such as HTML, plain text, or other XML structures. It defines a set of rules to match elements in the source XML and output the desired format. XSLT allows for dynamic transformations and is widely used in data conversion and web development. <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <body> <h1><xsl:value-of select="note/heading"/></h1> <p><xsl:value-of select="note/body"/></p> </body> </html> </xsl:template> </xsl:stylesheet>

What is XML?
XML stands for eXtensible Markup Language. It is a markup language designed for storing and transporting data. The primary purpose of XML is to allow data to be shared across different systems, especially via the internet. Unlike HTML, XML is focused on data representation rather than presentation. It is both human-readable and machine-readable. <note> <to>Tove</to> <from>Jani</from> <heading>Reminder</heading> <body>Don't forget me this weekend!</body> </note>

What are CDATA sections in XML?
CDATA sections in XML are used to include text that should not be parsed by the XML parser. Any data enclosed within a CDATA section is treated as character data and not as markup. CDATA sections are particularly useful when embedding code snippets or special characters that might otherwise interfere with the XML parsing. <![CDATA[This is <b>bold</b> text]]>

What is a well-formed XML document?
A well-formed XML document adheres to the basic syntax rules of XML. These include the following: 1. It must have a single root element. 2. All elements must be properly closed. 3. Tags must be properly nested. 4. Attribute values must be enclosed in quotes. 5. It is case-sensitive. A well-formed XML document can be parsed correctly by an XML parser. <book> <title>XML Basics</title> <author>John Doe</author> </book>

What is an XML Schema?
An XML Schema defines the structure and rules for an XML document. It specifies what elements and attributes are allowed, their data types, and how they are related to each other. XML Schemas ensure that the XML document is valid and follows a predefined structure, which helps in data consistency across systems. <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="note" type="xs:string" /> </xs:schema>

What is Flutter?
Flutter is an open-source UI software development toolkit created by Google. It allows developers to build natively compiled applications for mobile, web, and desktop from a single codebase. Key features include a rich set of pre-designed widgets, hot reload, and high performance. For instance, using Flutter, you can create a beautiful mobile app with minimal code.

What is a Stateless Widget?
A Stateless Widget is immutable and cannot change its state once built. It's used when the UI doesn't depend on any data that might change. For instance, a text label that always displays the same text can be implemented as a Stateless Widget, as it doesn't require any dynamic updates.

How does the Flutter framework handle animations?
Flutter offers powerful animation capabilities through its Animation class and related widgets. You can create smooth animations using 'AnimatedBuilder' or 'TweenAnimationBuilder.' For instance, to animate a button's color, you can use an AnimationController to define the duration and Tween for color interpolation.

What is the difference between Navigator.push and Navigator.pushReplacement?
Navigator.push adds a new route on top of the current one, allowing users to return to the previous screen. In contrast, Navigator.pushReplacement replaces the current route with a new one, removing the previous route from the stack. For example, using push for a login screen allows users to return to the previous screen, while pushReplacement would not.

What is the Java Virtual Machine (JVM)?
The Java Virtual Machine (JVM) is an abstract computing machine that enables Java bytecode to be executed. It provides an environment where Java programs can run, converting bytecode into machine code for the host machine. This allows Java to be platform-independent and portable across different systems.

What are Java interfaces?
Java interfaces are abstract types that define a contract for classes without providing implementation. Unlike classes, interfaces cannot hold state and only declare methods. A class can implement multiple interfaces, allowing for more flexible designs. For instance, an 'Animal' interface may include methods like 'eat()' and 'sleep()'. How do interfaces differ from classes?

What is the difference between .xls and .xlsx?
The .xls format is a binary file format used by Excel 97-2003, whereas .xlsx is an XML-based format introduced in Excel 2007. The .xlsx format allows for larger files and enhanced features like improved data recovery and better compression. For example, .xlsx files typically use less disk space.

What is the use of VLOOKUP in Excel?
VLOOKUP is used to search for a value in the first column of a table and return a value in the same row from another column. For example, if you have a table with employee IDs and names, you can use VLOOKUP to find an employee's name using their ID.

What is the purpose of the CONCATENATE function?
The CONCATENATE function combines multiple text strings into one. For example, CONCATENATE('Hello', ' ', 'World') results in 'Hello World.' This is useful for creating full names from separate first and last names or merging data from multiple columns into a single column.

What is Axios and why is it used?
Axios is a popular JavaScript library used for making HTTP requests from a browser or Node.js. It simplifies the process of sending asynchronous HTTP requests to REST endpoints. Developers use it for easy handling of network requests like GET, POST, PUT, DELETE, and PATCH. axios.get('/user').then(response => console.log(response));

How do you send data using a POST request in Axios?
In Axios, you can send data using a POST request with `axios.post()`. It accepts two parameters: the URL and the data to be sent in the request body. This method is often used to create new resources or send form data to a server. axios.post('/user', { firstName: 'John', lastName: 'Doe' }).then(response => console.log(response));
