A class is a blueprint for creating objects, which are instances of classes that have attributes and behaviors.

• Classes define the structure and behavior of objects.

• Objects are instances of classes that have attributes (fields) and behaviors (methods).

• Classes can inherit attributes and behaviors from other classes through inheritance.

• Example: Class 'Car' can have attributes like 'color' and behaviors like 'drive'. An ob...read more

OOPs principles are the foundation of object-oriented programming, including concepts like inheritance, encapsulation, polymorphism, and abstraction.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Polymorphism: Ability to present the same interface for different data types.

• Abstraction: Hiding the compl...read more

• Sort the list in descending order

• Access the element at index 1 to get the second largest element

State is mutable data managed within a component, while props are immutable data passed from parent to child components.

• State is managed within a component and can be updated using setState() method

• Props are passed from parent to child components and cannot be changed within the child component

• State is used for managing component-specific data, while props are used for passing data between components

State is mutable data managed by a component, while props are read-only data passed from parent to child components.

• State is managed within a component and can be updated using setState() method

• Props are passed from parent to child components and cannot be modified by the child component

• State is used for managing component-specific data, while props are used for passing data between components

Life cycle methods in React.js are special methods that are automatically called at specific points in a component's life cycle.

• Life cycle methods include componentDidMount, componentDidUpdate, componentWillUnmount, etc.

• componentDidMount is called after the component has been rendered to the DOM.

• componentDidUpdate is called after the component's state or props have been updated.

• Similar to componentDidMount and componentDidUpdate in class components

• Takes a function as its first argument and an optional array of dependencies as its second argument

• Dependencies array controls when the effect is re-run

Creating planes in CAD involves various methods to define 2D surfaces for modeling and design.

• Using the 'Plane' tool to create a standard plane at a specified location.

• Defining a plane through three points in 3D space for custom orientations.

• Creating a plane parallel to an existing face or surface for alignment.

• Utilizing construction geometry to establish reference planes for complex designs.

• Employing offset planes to ...read more
