Ans: CORS refers to Cross-Origin Resource Sharing. This is a safety feature used by web browsers that permits the resources displayed on a website page to be requested from another domain other than that from which the first resource was delivered. This is crucial for web applications that depend on APIs from different domains as it allows the web application to access data stored on third-party servers safely.
Ans: Something that I find interesting about myself is that I have a love for cooking and love experimenting with different food styles. It is an excellent way to relax as a coder after a long and tiring day.
Ans: Yes, I'm familiar with design patterns. Design patterns are reusable solutions to software design issues. Design patterns help in improving the efficiency, flexibility, and accuracy of code.

Ans: Long polling is a technique commonly used in web development to facilitate real-time communication between a client and a server. Instead of the client repeatedly requesting updates, the server keeps the request open until new data is available and then sends the updated information to the client. This method is faster and more efficient than traditional polling, resulting in a better user experience and conserving server resources.
Ans: The programming language I need to know depends on the specific project and its requirements. But I am open to learning new things; however, I have found that JavaScript, Python, and Java are some of the commonly required languages, and I am working on all of them.

Ans: The latest trends in Full Stack development include serverless architecture, microservices, containerization, and artificial intelligence. To stay updated about new trends, I participate in online communities, attend conferences and workshops, subscribe to technology blogs and newsletters, and continuously learn and explore new tools and technologies.
Ans: To optimize a website for efficiency and scalability, there are several ways:
Ans: Full Stack Web Developers work on developing and maintaining websites and web applications. They take care of both front-end and back-end. They use their expertise in programming languages, frameworks, and designing tools to meet clients' requirements.
Ans: Full Stack Developers must be proficient in the latest programming languages, such as HTML, CSS, JavaScript, and server-side languages, such as Java, Python, Ruby, or PHP and have experience working with databases and have knowledge of SQL or NoSQL and various frameworks, libraries, and tools for web development, such as React, Angular, Node.js, and Express.js. In addition, they should have excellent problem-solving, communication, and collaboration skills.
Ans: Referential transparency is functional programming that refers to the ability to replace an expression with its corresponding value without changing the program's behaviour. This means a function should return the same output for a given input, regardless of where it is called in the program.
Ans: MVC and MVP are architectural patterns used in software development. MVC stands for Model-View-Controller, while MVP stands for Model-View-Presenter. MVC and MVP have similar architectures but differ in handling user input and data flow. MVC separates the application into three components: the model (data), the view (user interface), and the controller (handles user input).
Ans: Referential transparency refers to the ability to replace an expression with its corresponding value without changing the behaviour of the program, the function should return the same output for a given input, regardless of where it is called in the program.
Ans: Semantic HTML is used to add value to the content on a web page. For example, <nav> tag is used to define a navigation menu on a web page instead of a <div> tag. Semantic HTML makes it easier for search engines to understand the content of a web page, making it more accessible for users with disabilities.

Ans: Becoming a full-stack developer is a challenging task that requires a combination of technical and non-technical skills. It requires a solid foundation in multiple programming languages, web development frameworks, databases, and front-end technologies. Moreover, full-stack developers need to have a good understanding of software development principles and design patterns. They should also be able to manage time and work under pressure while maintaining high quality. However, with dedication, hard work, and constant learning, anyone can become a successful full-stack developer.
Ans: There are several ways to reduce the load time of a web application, such as:
Ans: Server-side scripting is executed on the server before the page is sent to the client's browser. It generates dynamic content based on user input, database queries, or external APIs. Examples of server-side scripting languages are PHP, Python, Ruby, and Java.
Client-side scripting, on the other hand, is executed in the browser after the page has been downloaded. It manipulates the HTML document and allows dynamic user interaction without a page refresh. Examples of client-side scripting languages are JavaScript, HTML5, and CSS3.
Ans: Temporal Dead Zone (TDZ) is a behavior introduced in ES6 that occurs when trying to access a variable declared using the let or const keyword before it has been initialized. In this case, a runtime error will be thrown. This is different from variables declared using var, which can be accessed before they are initialized but will return an undefined value.
Ans: Referential transparency is a property of functions in functional programming, where a function always returns the same output for the same input without causing any side effects. In other words, it is a guarantee that a function can be replaced with its return value without affecting the correctness of the program. This property makes it easier to reason about code and helps to ensure that functions are composable and reusable.
Ans: Arrow functions have some limitations, such as not being able to bind this keyword, not supporting the arguments object, and not being able to use the new keyword to create objects. Therefore, they should not be used in certain situations where these limitations would cause issues. However, in most cases, arrow functions can be used effectively and are a concise and readable way to write functions.
Ans: Session management is a crucial aspect of web development, and it involves maintaining the state of user interactions with the application. In Java Servlets, there are three main methods of session management:
Ans: Double brace initialization is a Java language feature that concisely allows for the creation and initialization of nested data structures. It involves using two sets of braces to create an anonymous inner class and initializing its instance variables. Double brace initialization is used when creating a collection of objects or a Map with initial values.
Ans: SOLID is an acronym for a set that stands for the five principles: Single Responsibility Principle, Open-Closed Principle, Liskov Substitution Principle, Interface Segregation Principle, and Dependency Inversion Principle. The SOLID principles help developers create modular, testable, and easy-to-maintain code.
Ans: Cross-Origin Resource Sharing (CORS) is a security mechanism that allows or restricts access to resources on a web page from different origins. In the context of MVC, CORS is used to manage the communication between different servers and domains. When a client requests a resource from a different domain, the server may need to send an Access-Control-Allow-Origin header in its response to indicate that the resource is accessible from the client domain. This helps prevent unauthorized access to resources and improves the security of web applications.
Ans: Grunt is a JavaScript task runner that helps automate repetitive actions, including minification, unit testing, compilation, etc.
Ans: Benefits of Grunt in the project include:
Ans: To install Grunt, you must first install Node.js and Node Package Manager ( npm).
Then run the command in the command prompt: 'npm install -grunt-cli.'
Gruntfiles can be created with the file name 'Gruntfile.js' in the project's root directory.
Ans: These are some popular Grunt plugins:
Ans: Command - 'grunt' followed by the task name is used to run the Grunt Task.
Suppose the file name is xyz. Syntax: grunt xyz
The significant difference between Grunt and Gulp is -
Grunt uses configuration files, whereas Gulp uses a code-baes approach – streams to work on the project.
Ans: Command: '—debug' is used to debut the Grunt task.
Ans: Yes, you can customize Grunt tasks.
Ans: To automate repetitive tasks using Grunt, you can create tasks that perform specific actions such as minifying files, running tests, or deploying your code. These tasks can be run automatically using a task runner like Grunt.
