在一般的移动端开发场景中，每次更新应用功能都是通过 Native 语言开发并通过应用市场版本分发来实现的。但是市场瞬息万变，Native 语言在开发效率上存在一定不足，并且从 APP 版本更新 到 应用市场审核发布 再到 用户下载更新，总会存在一定的时间差，这样就导致新的功能无法及时覆盖全量用户。
为了解决这个问题，开发者们一般会在项目里引入一门脚本语言，提速 APP 的研发流程。在移动端应用比较广泛的脚本语言有 Lua 和 JavaScript，前者在游戏领域用的比较多，后者在应用领域用的比较多。本篇文章主要是想探讨一下移动双端（iOS & Android）的 JavaScript 引擎选型。由于个人水平有限，文章总会有遗漏和不足的地方，还请各位大佬多多指教。
A while ago, a senior person at our company learned through some channels that a certain national-level APP was rejected for three months because Apple App Store reviewers detected React Native hot update content. Our hot update platform has similar principles to the problematic APP, so we also face the risk of rejection. Therefore, we need to think of some ways to hide the hot update bundle and avoid being discovered by reviewers.
Actually, this problem is quite complex because it's not purely a technical issue but also involves various complex commercial interests. Under many constraints, it's difficult to find an optimal solution. Moreover, this issue is quite sensitive, so I can only briefly outline my thinking process. This article will not provide specific code implementations.
Serious declaration: If anyone hides hot update data according to the ideas in this article and the application gets rejected or removed, I will not be responsible.
This article was originally a Zhihu answer, which received good response, so I refined some details and reorganized it for publication
On December 17, 2020, PaperClip Studio launched a new product - "The Birth of an Artificial Intelligence" Interactive Teaching Video. Because I've been exposed to MOOCs since high school and have always been very interested in online education, I immediately followed up and experienced their trial lesson - "Recognizing Numbers".
This article contains some of my insights after studying multiple platform UI frameworks. Due to limitations in energy and technical expertise, there are inevitably shortcomings in this article. Please feel free to provide guidance.
Today let's talk about the practical application of De Morgan's laws in programming. The title looks intimidating, but actually you only need a little bit of high school math knowledge to understand it. Moreover, this knowledge can be quickly applied to projects after mastering it, with a very high investment-return ratio.
React Native as a cross-platform framework has one of the most headache-inducing problems: version updates. Especially when encountering major version updates, the configuration and build files for JavaScript, iOS, and Android all undergo significant changes. Sometimes these configuration files are coupled together, where one change affects everything.
In 2020, if I had to recommend a data collection software for the general public, it would definitely be Houyi Web Scraper. Compared to the web scraper I previously recommended, if web scraper is a small and precise Swiss army knife, then Houyi Web Scraper is a large and comprehensive heavy weapon that can basically solve all data scraping problems.
Let's discuss the excellent features of this software.

This article assumes that the person leading the React Native upgrade is a frontend developer who is familiar with JavaScript-based frontend build processes. If conditions permit, it's strongly recommended to involve iOS and Android developers during the upgrade. For some trivial upgrade details, face-to-face communication is far more efficient than search engines.
