我一直在学习前端开发，而让我一直感到困扰的一件事就是试图理解 JavaScript 错误消息。有些错误消息很清晰，但很多在你刚入门的时候看起来却很晦涩难懂。我想要一个工具，它不仅告诉我错误是什么，还要告诉我为什么会发生这个错误，以及我接下来应该关注什么。所以我构建了一个基于浏览器的、小型的工具，它可以接收 JS 错误并用更简单的语言进行解释。它还建议可能的原因和需要检查的事项。所有操作都在浏览器本地运行——没有后端，不存储任何数据。它的功能：解析错误消息用通俗易懂的语言解释错误建议可能的原因提供可能的下一步操作简洁、极简的 UI完全在客户端运行我非常欢迎大家对这个工具的任何方面提出反馈意见。链接：https://jsdebugger.netlify.app网站上也有一个反馈区。我正在积极改进它，并很乐意听取 HN 社区的意见。

I’ve been learning frontend development, and one thing that consistently slowed me down was trying to understand JavaScript error messages. Some are clear, but many feel cryptic when you’re still early in your journey. I wanted something that didn’t just tell me what the error was, but why it happened and what I should look at next.So I built a small browser‑based tool that takes a JS error and explains it in simpler language. It also suggests possible causes and things to check. Everything runs locally in the browser — no backend, no data stored.What it does:Parses the error messageExplains it in plain EnglishSuggests likely causesOffers possible next stepsSimple, minimal UIWorks entirely client‑sideI'd appreciate feedback on literally anything on the tool.Link: https://jsdebugger.netlify.appThere’s a feedback section on the site as well. I’m actively improving it and would love to hear what the HN community thinks.
