EJS
Eloquent JavaScript 5 features
ProBackup 4 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.
  • Instant Access to Historical Versions
    Navigate backups effortlessly with our intuitive interface. Compare past versions of your data, metadata, and files, and quickly locate the backup you need for tables, records, comments, and field configurations.
  • Smart Integrity Checks & Proactive Alerts
    We go beyond simple backups. ProBackup continuously monitors your data, alerting you if something seems off—like a sudden drop in the number of backed-up tables. Stay informed with automated weekly status reports.
  • One-Click, Granular Restore
    Recover deleted records, tables, and more in just a few clicks. Our restore process ensures that all related data, such as comments and files, are recovered together.
  • Sync Backups to Google Drive
    Keep an additional copy of your data in Google Drive. Sync your records to Google Sheets and automate the download of attachments to your local device.

Questions & Answers

As answered by people managing Eloquent JavaScript and ProBackup.

Which are the primary technologies used for building your product?

ProBackup's answer:

Infrastructure runs on AWS. Backup files are stored in AWS S3 and metadata (IDs, tree structure, webhook registrations) in AWS RDS, encrypted at rest with AES-256 via AWS Key Management Service. Customers can choose from nine AWS regions (Ireland, Frankfurt, London, North Virginia, Montreal, São Paulo, Sydney, Singapore, Tel Aviv). ProBackup connects to each source app through its official API over OAuth, with all tokens AES-256 encrypted using unique initialization vectors. Data in transit is secured via SSL/TLS on port 443, enforced with HSTS. The backup engine is incremental and versioned, creating independent snapshots each cycle.

What's the story behind your product?

ProBackup's answer:

ProBackup started in 2017 as Momentum Tools, originally built to back up Podio. As more teams moved their operations into a growing range of SaaS apps and hit the same blind spot — that vendors don't protect customer data from customer-side mistakes — the product expanded. In August 2020 it relaunched under the ProBackup brand, adding Asana as the first new platform, and grew steadily from there to cover 20+ apps. A major platform refresh came in September 2023, SOC 2 compliance was achieved in May 2025, and the current version (3.0), with a completely redesigned UI, launched in August 2025. Today ProBackup is a lean, product-led company (ProBackup BV) serving ~2,500 customers.

What makes your product unique?

ProBackup's answer:

ProBackup is purpose-built for SaaS productivity and CRM apps — not files or servers. It backs up the data living inside Asana, ClickUp, Monday, Airtable, HubSpot, Trello, Notion, Jira, Slack, Podio, and 20+ other tools, fully automatically every 24 hours. The key insight: your SaaS vendor backs up their own infrastructure for their disaster recovery, not to protect your work. If your team — or an AI agent acting inside the app — deletes or overwrites a record, the vendor can't bring it back. That gap is what ProBackup fills. Backups are incremental and versioned, so you get point-in-time recovery and can restore exactly what you need: a single field, a comment, a whole project. Optional Google Drive sync adds a second, independent layer of redundancy you control.

Why should a person choose your product over its competitors?

ProBackup's answer:

A few reasons. Breadth: one account covers 20+ platforms, and you can add unlimited apps on any plan. Granularity: restore a single record or an entire board, with point-in-time recovery to any previous day. No setup overhead: backups run automatically every 24 hours — no scheduling, no maintenance. Independent redundancy: unlike tools that dump a new CSV after every cycle, ProBackup syncs to a live Google Sheet you own, so you keep a usable copy even if ProBackup is unavailable. And trust: SOC 2 compliant, AES-256 encryption, isolated key management (no one at ProBackup can read your raw data), and a choice of nine AWS storage regions worldwide. It's a focused, product-led tool — self-serve onboarding, simple UI, transparent pricing.

How would you describe the primary audience of your product?

ProBackup's answer:

Teams that run their daily operations inside SaaS productivity and CRM apps and can't afford to lose that data — typically SMBs and mid-market companies, often without a dedicated IT/backup function. The buyer is usually the admin, operations lead, or team owner responsible for an Asana, ClickUp, Monday, HubSpot, or Airtable workspace who recognizes that accidental deletion, a rogue integration, a departing employee, or an AI agent gone wrong could wipe out work the vendor won't restore. ~2,500 customers today, with a 35% trial-to-paid conversion rate.

    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
