# 优职 vs JavaScript Starter

The clearest difference is iOS requirement: 优职 at 12.0 against JavaScript Starter's 17.0. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 优职 sells 3 one-off in-app purchases and JavaScript Starter sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
