The DOM is a programming interface that represents HTML and XML documents as a tree structure, enabling dynamic content manipulation.

• The DOM represents the document structure as a tree of nodes, where each node corresponds to a part of the document (e.g., elements, attributes).

• JavaScript can interact with the DOM to change the document's content, structure, and style dynamically. For example, using `document.getElement...read more

An array is a collection of items stored at contiguous memory locations, allowing efficient access and manipulation of data.

• Arrays can hold multiple values of the same data type, e.g., ['apple', 'banana', 'cherry'].

• They are indexed, meaning each element can be accessed using its index, e.g., array[0] returns 'apple'.

• Arrays have a fixed size, defined at the time of creation, e.g., int[] numbers = new int[5];

• They allow f...read more

A stack is LIFO (Last In, First Out), while a queue is FIFO (First In, First Out) for managing data.

• Stack operations: push (add), pop (remove), peek (view top). Example: Undo feature in text editors.

• Queue operations: enqueue (add), dequeue (remove), front (view first). Example: Print job management.

• Stacks are used in function call management, while queues are used in task scheduling.

• In a stack, the last element added i...read more

A data structure is a way to organize and store data for efficient access and modification.

• 1. Types: Common data structures include arrays, linked lists, stacks, queues, trees, and graphs.

• 2. Arrays: Fixed-size collections of elements, e.g., [1, 2, 3].

• 3. Linked Lists: Collections of nodes where each node points to the next, e.g., 1 -> 2 -> 3.

• 4. Stacks: Last-in, first-out (LIFO) structure, e.g., function call stack...read more

OOP is a programming paradigm based on objects that encapsulate data and behavior, promoting code reusability and modularity.

• Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).

• Abstraction: Hiding complex implementation details and showing only essential features (e.g., using interfaces).

• Inheritance: Creating new classes based on existing ones to promote code reuse (e.g., a...read more
