EJS
Eloquent JavaScript 5 features

  • 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.

Questions & Answers

As answered by people managing Eloquent JavaScript and Usejarvis.

What makes your product unique?

Usejarvis's answer:

Jarvis combines awareness of your daily work with memory of your company’s goals to identify what’s worth automating. It turns those opportunities into reusable workflows, using code for predictable steps and AI where judgement is needed.

Why should a person choose your product over its competitors?

Usejarvis's answer:

Jarvis helps with both deciding what to automate and creating the workflow. Its company memory and awareness of daily work help make automation relevant to your priorities.

How would you describe the primary audience of your product?

Usejarvis's answer:

Founders and small teams who spend too much time on repetitive digital work, from sales follow-ups to research and reporting, and want to automate it without becoming automation specialists.

What's the story behind your product?

Usejarvis's answer:

We built Jarvis out of the frustration of running companies while repetitive work kept piling up. Even with AI and automation tools, we still had to decide what to automate and configure it ourselves, so we set out to build software that understands the business and helps carry that workload.

Which are the primary technologies used for building your product?

Usejarvis's answer:

Jarvis combines large language models, persistent company memory and a workflow engine that mixes code execution with AI reasoning, alongside browser and desktop automation.

    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
