よくある活用例

• 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.
