JavaScript格式化工具

为压缩后的JavaScript添加缩进，并在分号和花括号处换行。

如何使用本工具

1
Paste or type your JavaScript into the input textarea.
2
Watch the indented version appear live in the output box below as you type — there is no Format button.
3
Select the formatted text in the output box and copy it with your keyboard (there is no copy button).
4
Scan the result for any line that split inside a string, regex, or comment, and fix those by hand if needed.

压缩后的代码包会移除所有空白：便于快速分发，却让人难以阅读。这个基础格式化工具会恢复缩进，并在分号和花括号处断行。如需保留注释、遵循ASI规则的生产级重新格式化，请使用Prettier或你编辑器内置的格式化工具。

Eyeballing a minified vendor bundle or one-line snippet to see its rough structure before debugging.
Quickly indenting a short config or object literal you pasted from a chat message or log line.
Spreading a dense JSON-like object across multiple lines so nesting becomes visible.
Teaching or demoing how braces and semicolons map to indentation levels for beginners.
Making a compressed third-party script readable enough to locate a specific function or variable.
Sanity-checking that brackets are balanced, since unbalanced input leaves the indentation visibly skewed.

它和Prettier一样好吗？▼

不：这只是快速的视觉修整。Prettier是基于解析器的正规格式化工具，能处理本工具无法应对的边界情况。
