# JavaScript Compiler vs Skill

The clearest difference is rating: Skill at 4.6 against JavaScript Compiler's 2.7. Skill also leads on review sentiment (31% vs 0%) and update cadence (fortnightly vs every 4 months). JavaScript Compiler's advantage is in-app purchases (none vs 11) and ads (none vs shown). On price there is nothing between them.

Both are free to download. Skill sells 10 in-app purchases, starting at $5.99 per month. JavaScript Compiler asks for nothing beyond the download.

Skill holds the better App Store score, 4.6 against 2.7. That said, the two scores are not equally well evidenced: Skill has 103 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 0% of JavaScript Compiler's written reviews are positive against 31% of Skill's.

JavaScript Compiler ships an update every 4 months, Skill fortnightly. The most recent releases landed on October 3, 2026 and October 5, 2026 respectively.
