  • 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.

Possible disadvantages

  • Cost
    OPAS might be expensive for smaller organizations or those with limited budgets, potentially posing a barrier to entry.
  • Complexity
    Despite its user-friendly interface, the depth of features might overwhelm new users, necessitating time and effort to become fully proficient.
  • Integration Challenges
    Integrating OPAS with other existing systems used within an organization might present challenges, requiring additional effort for seamless operation.
  • Dependency on Internet
    As a cloud-based solution, OPAS requires a reliable internet connection, which could be a limitation in areas with poor connectivity.
  • Periodic Updates
    Frequent updates may necessitate continuous learning and adaptation from users, potentially disrupting workflow with new features and interfaces.

  • My Azure Cloud Resume Challenge Journey
    If you haven’t read Eloquent JavaScript , go check it out. It’s one of my all-time favourite programming books — hands down. - Source: dev.to / about 1 year ago
  • How do we learn to get good at programming
    Videos, blogs, text-based teachings, YouTube project-based learning, books, and the like are all examples of various methods and mediums of acquiring skills, especially in the software engineering industry. As I continue to navigate... - Source: dev.to / almost 2 years ago
  • 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

  • Need help with international shipping.
    I've used a few over the years but lately https://opas.com/ has been my go to. Really fast service, easy to use UI with multiple shipping options (depending on destination). From a cursory look they seem to ship to Japan. Source: almost 4 years ago
  • Where do you get original parts that ship online and legit?
    Try opas.com, a forwarding service that gives you a US address to order to. Cannot guarantee that they service Israel (I am in Sweden), but should do. Worked like a charm for me to get hold of a rare spare part for an old outboard motor... Source: about 4 years ago
  • Is YouShop in fact the cheapest USA-to-NZ shipping forwarder?
    I really rate OPAS (referral link, non referral link here). Multiple shipping options, fewer restrictions (Youshop won't handle Li-Ion batteries) and you get 20% off your first shipment. Source: about 4 years ago
