• Static websites are built using only HTML and CSS, with no server-side processing involved.

• Dynamic websites use server-side scripting languages like PHP, Python, or Ruby to generate content on the fly.

• Static websites are faster to load as they do not require server processing for each request.

• Dynamic websites can provide personalized content to users bas...read more

The question covers topics related to hash tables, constructors, and string reversal in Python.

• Hash tables are data structures that allow for efficient lookup, insertion, and deletion of key-value pairs.

• Constructors are special methods that are called when an object is created and are used to initialize its attributes.

• In Python, strings can be reversed using slicing or the built-in reversed() function.

Promise in JavaScript is an object representing the eventual completion or failure of an asynchronous operation.

• Promises are used to handle asynchronous operations in JavaScript.

• They can be in one of three states: pending, fulfilled, or rejected.

• Promises can be chained using .then() to handle success and .catch() to handle errors.

• Example: const myPromise = new Promise((resolve, reject) => { ... });

Read-only is a runtime concept while const is a compile-time concept.

• Read-only variables can be assigned a value only once during runtime.

• Const variables are initialized at compile-time and cannot be modified during runtime.

• Read-only variables can be assigned a value in the constructor of a class.

• Const variables can be used to define constant values like pi or e.

• Read-only variables are declared using the 'readonly' keyword.

• Const variables are declared using the 'const' keywor...read more

JavaScript is a high-level, interpreted programming language used for creating interactive websites and web applications.

• JavaScript is a client-side scripting language that runs in the browser.

• It is used to add interactivity, animations, and dynamic content to websites.

• JavaScript can also be used on the server-side with Node.js.

React JS is a JavaScript library for building user interfaces.

• React JS allows developers to create reusable UI components.

• It uses a virtual DOM for better performance by updating only the necessary parts of the actual DOM.

• React JS follows a unidirectional data flow, making it easier to manage state and props.

• It is commonly used in single-page applications and for building interactive web interfaces.

The out keyword is used to pass arguments as reference parameters in C#.

• The out keyword is used to return multiple values from a method.

• The out keyword must be used in both the method signature and the method call.

• The out keyword initializes the variable passed as an argument within the method.

• The out keyword is similar to the ref keyword, but the variable passed as an argument does not need to be initialized before the method call.
