# Javascript教程 vs 主内阅读

The clearest difference is in-app purchases: 主内阅读 at none against Javascript教程's 1. 主内阅读 also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 4 months). Javascript教程's advantage is review sentiment (100% vs 83%). On price and device support there is nothing between them.

Both are free to download. Javascript教程 sells 1 one-off in-app purchase. 主内阅读 asks for nothing beyond the download.

Javascript教程 ships an update every 4 months, 主内阅读 every 3 weeks. The most recent releases landed on June 20, 2026 and August 24, 2026 respectively.
