Redux is a predictable state container for JavaScript apps.

• Redux is a state management library for JavaScript applications.

• It helps in managing the state of an application in a predictable way.

• Redux follows a unidirectional data flow architecture.

• It uses actions, reducers, and a store to manage the state of an application.

• Redux is commonly used with React to build scalable and maintainable applications.

Higher order function takes a function as an argument or returns a function. Higher order component is a function that takes a component and returns a new component.

• Higher order function is a function that operates on other functions, either by taking them as arguments or by returning them.

• Higher order component is a function that takes a component and returns a new component with additional functionality.

• Higher order functions and components are used to create reusable code ...read more

Pharmacokinetics is the study of how drugs move through the body, while pharmacodynamics is the study of how drugs interact with the body to produce their effects.

• Pharmacokinetics focuses on drug absorption, distribution, metabolism, and excretion in the body

• Pharmacodynamics examines how drugs interact with receptors to produce their therapeutic or toxic effects

• Understanding both pharmacokinetics and pharmacodynamics is crucial in determining the appropriate dosage and treatm...read more

Functional components are stateless and use functional programming concepts, while class-based components are stateful and use object-oriented programming concepts.

• Functional components are simpler and easier to read and test.

• Class-based components have access to lifecycle methods and state.

• Functional components are preferred for simple UI components, while class-based components are preferred for complex UI components.

• Functional components can be written as arrow functions, ...read more

Block components take up the full width of their container, while inline components only take up the necessary space.

• Block components create a new line and take up the full width of their container

• Inline components only take up the necessary space and do not create a new line

• Block components are used for larger elements like paragraphs and headings

• Inline components are used for smaller elements like links and buttons

React is a JavaScript library for building user interfaces.

• React allows for building reusable UI components.

• It uses a virtual DOM for efficient rendering.

• React can be used for both web and mobile app development.

• It supports server-side rendering for improved SEO.

• React is maintained by Facebook and has a large community of developers.

Lock and key mechanism is a concept in biochemistry where a specific enzyme fits perfectly with a specific substrate, similar to a lock and key.

• Enzymes act as keys that fit into specific substrates like locks

• The specificity of the interaction ensures that only the correct substrate can bind to the enzyme

• This mechanism is crucial for various biological processes such as digestion and metabolism

React has two types of hook methods: State Hooks and Effect Hooks.

• State Hooks manage state in functional components.

• Effect Hooks manage side effects in functional components.

• useState() is an example of State Hook.

• useEffect() is an example of Effect Hook.

IUPAC names for few molecules

• IUPAC names are systematic names given to molecules based on their structure

• Examples include ethane (C2H6), methanol (CH3OH), and butanoic acid (C4H8O2)

• IUPAC names follow a set of rules to ensure consistency and clarity in naming

• They often include prefixes and suffixes to indicate functional groups and substituents

• Knowing IUPAC names is important for communication in the scientific community

ADME stands for Absorption, Distribution, Metabolism, and Excretion. PK is Pharmacokinetics and PD is Pharmacodynamics.

• ADME refers to the processes that a drug undergoes in the body - absorption, distribution, metabolism, and excretion.

• PK involves the study of how the body affects a drug, including its absorption, distribution, metabolism, and excretion.

• PD focuses on how a drug affects the body, including its mechanism of action and therapeutic effects.

• Understanding ADME, PK,...read more

Angular is a full-fledged framework while React is a library for building UI components.

• Angular is a complete solution for building web applications while React is focused on building UI components.

• Angular uses two-way data binding while React uses one-way data flow.

• Angular has a steeper learning curve while React is easier to learn.

• Angular has a larger file size while React has a smaller file size.

• Angular has a built-in dependency injection system while React does not.

• Angula...read more

Lazy loading is a technique used to defer the loading of non-critical resources until they are needed.

• Lazy loading can improve the performance of a React application by reducing the initial load time.

• React.lazy() is a built-in function that allows for lazy loading of components.

• Code splitting can be used to split the application into smaller chunks that can be loaded on demand.

• Lazy loading can be used for images, videos, and other resources that are not immediately necessary....read more

Semantic structure of HTML refers to using HTML elements to properly structure and organize content for better accessibility and SEO.

• Semantic HTML elements provide meaning to the content, making it easier for search engines to understand and index the page.

• Examples of semantic elements include <header>, <nav>, <article>, <section>, <aside>, <footer>, <main>, <figure>, <figcaption>.

• Using semantic elements improves accessibility for users with disabilities, as screen readers ca...read more

Patents are legal protections granted by the government to inventors, giving them exclusive rights to their inventions for a certain period of time.

• Patents provide inventors with the exclusive right to make, use, and sell their inventions for a limited period of time.

• They encourage innovation by rewarding inventors with a temporary monopoly on their creations.

• Patents can cover a wide range of inventions, including products, processes, and designs.
