Main difference between struct and class.
- The main difference between struct and class in Swift lies in the way they store and manage data: struct is a value type and class is a reference type.
- Struct stores independent copies of data, while class shares reference to the same object.
- Struct does not support inheritance, while class supports inheritance.
- Class has deinitializer for cleanup when object is removed from memory, and classes can change properties without needing 'mutating' keyword.

- Crafting effective prompts involves iterating, evaluating, and templatizing queries.
- Quality prompts lead to better AI model output, saving time and improving results.
- Iteration is key: start simple, test the output, refine, and iterate further for specificity.
- By refining prompts iteratively, you can achieve accurate and relevant responses.
- A prompt template example for generating SQL queries is provided, emphasizing metadata and user instructions.
- An example prompt involving generating a BigQuery SQL query based on metadata and user requirements is demonstrated.
- The sample prompt leads to the generation of a specific SQL query for calculating total deposits of yesterday.
- Submitting the prompt to LLM resulted in a BigQuery SQL query for total deposits of yesterday.
- Crafting precise prompts is essential for AI models to provide contextually appropriate responses.

Why LLMs Aren’t Fully Deterministic?
- LLMs like ChatGPT are considered stochastic due to their probabilistic nature.
- LLMs are not fully deterministic because they use probabilities to generate responses based on learned patterns.
- LLMs predict the next word based on probabilities, leading to variations in output even with the same input.
- Stochasticity in LLMs allows for creativity and adaptability in generating varied responses.

HTMX Best Practices: Building Responsive Web Apps Without JavaScript Frameworks
- HTMX is a library that enables interactive web applications without heavy JavaScript frameworks, simplifying the client-side code and enhancing user experience.
- Best practices for working with HTMX involve setting it up, structuring HTML, avoiding complex loops, optimizing performance, and handling errors gracefully.
- To start with HTMX, include the library script, then use attributes like hx-get and hx-post to define dynamic behaviors in HTML elements.
- Dynamic content rendering without for loops can be achieved by processing data server-side and returning HTML fragments to be displayed using HTMX.
- Optimizing performance with HTMX includes minimizing requests, implementing caching, and debouncing requests to improve app efficiency.
- HTMX simplifies error handling by allowing the specification of actions for different events like responseError, providing a graceful user experience.
- HTMX offers simple integration, improved performance with server-side rendering, and avoids the complexity of full client-side frameworks.
- However, HTMX may have limited interactivity compared to comprehensive JavaScript frameworks and requires careful server-side logic for dynamic content.
- By following HTMX best practices, developers can build modern, responsive web apps with minimal effort and clean, straightforward implementations.
- Handling dynamic content on the server side and sending HTML fragments directly to the client can maintain application cleanliness and support platforms like DEV.to.
