EJS
Eloquent JavaScript 5 features
21 Days 5 features
  • 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.
  • Structured Program
    The 21 Days program provides a structured approach to forming new habits, making it easier for participants to stay on track.
  • Time-Bound Commitment
    With a specific 21-day timeframe, participants are motivated to commit to the program and potentially see faster results.
  • Habit Formation
    Focusing on repeating tasks over 21 days aligns with conventional wisdom about the time it takes to form new habits.
  • Community Support
    Participants often have access to a community of like-minded individuals, providing support and motivation throughout the process.
  • Variety of Programs
    21 Days offers a variety of programs catering to different goals, such as fitness, mindfulness, and productivity.

Possible disadvantages

  • Limited Flexibility
    A strict 21-days timeframe may not suit everyone, and could be challenging for those with unpredictable schedules.
  • One-Size-Fits-All Approach
    The program might not accommodate specific personal needs or adapt to varying levels of individual progress.
  • Sustainability Concerns
    After the initial 21 days, participants may struggle to maintain their new habits without continued guidance and support.
  • Pressure to Succeed
    The fixed duration can create pressure, leading to stress if individuals feel they are not progressing as expected.
  • Cost Implications
    Access to certain features or programs within the 21 Days platform may require a financial investment, which might not be feasible for all users.

  • Ask HN: Changing my mind about JavaScript
    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
