Eloquent JavaScript VS Cogmind

• Comprehensive Learning Resource
  Eloquent JavaScript covers a wide range of topics, from basic syntax to advanced concepts like asynchronous programming and web development. This depth makes it a valuable resource for both beginners and advanced programmers.
• Interactive Code Examples
  The book contains numerous interactive code examples that allow readers to see the effects of their code in real-time. This hands-on approach reinforces learning and helps solidify concepts.
• Free Online Access
  Eloquent JavaScript is available for free online, making it accessible to anyone with an internet connection. This allows learners from around the world to benefit from its content without financial barriers.
• Engaging Writing Style
  The author, Marijn Haverbeke, writes in an engaging and clear style, making complex topics more understandable and keeping readers interested.
• Good Balance of Theory and Practice
  The book strikes a good balance between theoretical explanations and practical exercises, allowing readers to apply what they have learned immediately.

Possible disadvantages

• Steep Learning Curve
  Some readers may find the book's progression to be rapid, especially if they are complete beginners. The book quickly moves from basic to more complex topics, which can be overwhelming.
• Lacks Visual Aids
  While the text is clear and the code examples are helpful, the book could benefit from more visual aids like diagrams and illustrations to explain complex concepts.
• Assumes Some Prior Knowledge
  Although it's aimed at beginners, the book sometimes assumes that readers have some prior programming experience, which can make it less accessible to absolute novices.
• Limited Coverage of Latest ES Features
  The book may not cover some of the latest features and best practices introduced in newer versions of JavaScript (e.g., ES2019 and beyond), meaning readers might need to supplement their learning with additional resources.
• Web Development Sections Could Be More Detailed
  While the book does touch on web development, the sections on this topic are not as in-depth as some readers might hope. Those looking to get a more thorough grounding in web development may need to consult other sources.

• Deep and innovative mechanics
  Cogmind features a unique robot-building system where players scavenge and attach parts to their body, creating a deeply strategic and ever-changing gameplay loop. The modular design encourages experimentation with different builds and playstyles.
• Exceptional ASCII and tileset art
  The game is renowned for its stunning ASCII-based presentation, with beautifully crafted visual effects, particle systems, and animations that push the boundaries of what traditional roguelike graphics can achieve. An optional tileset is also available for those who prefer it.
• Rich world-building and lore
  Cogmind features an intricate sci-fi world with multiple factions, hidden storylines, and deep lore that players can uncover through exploration, hacking terminals, and interacting with various NPCs and robot factions throughout the complex.
• High replayability
  With multiple routes, branching paths, secret areas, numerous endings, and a vast array of possible builds, every run feels different. The procedurally generated maps and varied strategic options ensure that the game stays fresh across hundreds of hours.
• Polished solo development
  Developed primarily by one person (Kyzrati), Cogmind is exceptionally polished and well-designed, with meticulous attention to detail in UI, sound design, mechanics, and quality-of-life features that rival or exceed many team-developed games.

Possible disadvantages

• Steep learning curve
  Cogmind can be overwhelming for newcomers due to its complex mechanics, numerous item types, and the amount of strategic knowledge needed to make meaningful progress. It takes many failed runs before players start to understand optimal strategies.
• Permadeath can feel punishing
  As a traditional roguelike with permadeath, losing a long and successful run to a single mistake or an unexpected encounter can be frustrating, especially given how invested players can become in their current build.
• Niche visual style
  Despite the quality of its ASCII art, the visual style is not for everyone. Some players may find it difficult to parse game information quickly or may simply prefer more conventional graphics, which can be a barrier to entry.
• Still in Early Access (long development)
  Cogmind has been in development and Early Access for many years. While the game is highly polished and content-rich, some players may be hesitant about the prolonged development cycle and the official 1.0 release timeline.
• Limited accessibility options
  The game's reliance on dense information displays, numerous keybindings, and fast-paced tactical decision-making can make it less accessible to players who prefer more streamlined or casual experiences, and accessibility features for disabilities are limited.

  Seconded. I won't recommend it and no one I know has recommended it for a decade. It's hard for someone who doesn't know JS to know which parts has changed and is no longer the way to do things. https://github.com/getify/You-Dont-Know-JS... - Source: Hacker News / about 2 years ago
