解析一个5M的文件，浏览器就崩溃了 (When parsing a 5M file, the browser crashes [?])

Thanks for the report, but I'm afraid I don't speak mandarin.

I've amended the title to the google translate translation: "When parsing a 5M file, the browser crashes",
but would require more information:

• which browser, OS, and how much RAM on the system.
• the error message encountered
• a test case to reproduce the behavior
• ideally, a suggestion of how out-of-memory situations should be handled.

Below is an automated translation of my response:

谢谢你的报告，但恐怕我不会说普通话。

我把标题修改为google翻译的翻译：“解析5M文件时，浏览器崩溃”，
但需要更多信息：

• 哪种浏览器、操作系统以及系统上有多少 RAM。
• 遇到的错误消息
• 重现行为的测试用例
• 理想情况下，建议如何处理内存不足的情况。

I wrote this page and I will attempt to help.

What I see is that the browser didn't crash. It hit an internal JavaScript processing timeout, stopped, and displayed the error.

I tried to reproduce it on all the browsers I have using 5-10 MB files, and they all worked fine.

While it may be possible to change the page to process the file in parts, it would be a major effort. However, it may be possible to avoid the problem by using a different browser, or changing the JavaScript timeout -- something that some browsers allow to do.

@dengnanhao, please try this and please provide us the data on your system, as @a2800276 suggested above.

我写了这个页面，我会回应。
您的浏览器没有崩溃。它遇到了处理页面的内部时间限制。然后它停止了处理并告诉了您。
我尝试了许多5到10MB的文件，使用了我所有的浏览器。它们都运行良好。
虽然可以通过修改页面来分部分处理文件，但这将是一项重大工作。
但是，不同的浏览器有不同的超时时间。一些浏览器允许您更改JavaScript超时值。
@dengnanhao, 请尝试此操作，并按照@a2800276上面的建议，请提供您系统上的数据。

Thank you very much for your reply. @rom-p @a2800276 The actual file size is close to 50MB. This is due to my calculation error and caused inconvenience to everyone. I am very sorry.

My testing environment:

1. Edge browser, version 123.0.242081 (official version) (64 bit)
2. Windows 11 operating system
3. Machine memory 24G

You are correct. In actual testing, files with a size of 5-10M can be parsed @rom-p . The first time I tested the file, the actual size was over 49M, close to 50M. During parsing, I timed out and waited for three consecutive times, causing the browser to crash.
Expect hexy.js to be like [hexed]（ https://hexed.it/ ）The provided functions are the same, capable of parsing large files
