iro.js is a JavaScript color picker widget that provides an SVG-based interface for selecting colors. It supports multiple color formats (hex, RGB, HSV, HSL, and kelvin temperatures) through a unified API, allows multiple colors for harmony selection, and requires no external dependencies. The library can be installed via NPM, CDN, or direct download, and offers customizable options, event handling, and easy integration with modern frameworks.

Task-based LLM routing directs incoming AI requests to the most suitable large language model based on the task. This approach improves performance, reduces costs, and enhances scalability by matching tasks with models optimized for those specific needs. For instance, simpler tasks can be routed to lightweight models like GPT-3.5 to minimize costs, while complex tasks are handled by more powerful models like GPT-4. This method also enhances reliability and latency, and is useful in diverse applications like customer support, content creation, code-related tasks, and multilingual processing.

Structured prompting is becoming a crucial skill for developers, akin to traditional coding practices. Using AI effectively involves treating prompts as modular, testable components within software systems. Techniques like few-shot prompting, chain-of-thought reasoning, self-consistency, skeleton prompting, and configuration parameters improve AI's coding outputs. Developers should rigorously validate and maintain prompts, just like any other code, to ensure reliability and consistency in AI-powered features.

Evan Wallace's WebGL Water demo showcases advanced graphics techniques like raytraced reflections, refractions, and heightfield water simulation. Users can interact with the simulation by creating ripples, rotating the camera, and moving objects. Some features require specific WebGL extensions for enhanced effects.

A comprehensive checklist covering frontend performance optimization techniques for 2025, including HTML optimization, CSS best practices, JavaScript management, image and video handling, font optimization, and server configuration.
