# Javascript教程 vs 书墨

The clearest difference is ads: 书墨 at none against Javascript教程's shown. 书墨 also leads on update cadence (every 5 days vs every 4 months) and ratings volume (6 vs 1). Javascript教程's advantage is review sentiment (100% vs 85%) and iOS requirement (15.0 vs 17.6). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Javascript教程 sells 1 one-off in-app purchase and 书墨 sells 2 in-app purchases, starting at $5.99 per year. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Javascript教程 against 5.0 for 书墨. That said, the two scores are not equally well evidenced: 书墨 has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 100% of Javascript教程's written reviews are positive against 85% of 书墨's.

Javascript教程 ships an update every 4 months, 书墨 every 5 days. The most recent releases landed on June 20, 2026 and September 15, 2026 respectively.
