Text Reverser

Reversing text means re-ordering the units of a string from last to first, but the result depends entirely on what you treat as a 'unit.' This tool exposes four units at once. Character reverse uses JavaScript's spread operator ([...text]), which iterates by Unicode code point rather than UTF-16 code unit, so most surrogate-pair characters and single emoji survive intact instead of splitting into broken halves. Word-order reverse splits on any run of whitespace (the /\s+/ regex) and flips the resulting list, so 'the quick fox' becomes 'fox quick the.' Per-word reverse keeps words in place but reverses the characters inside each one ('hello world' becomes 'olleh dlrow'). Line reverse splits on newline characters and flips line order, useful for log files or stacked lists. The character mode is a naive code-point reversal, not a grapheme-cluster reversal: combining accents, ZWJ-joined emoji like the family glyph, and flag sequences can still break apart because they span multiple code points. For Unicode-correct grapheme handling you would need Intl.Segmenter or a library such as grapheme-splitter.
