Formula & Theory — Uppercase to Lowercase Converter
There is no numeric formula; the Uppercase to Lowercase Converter applies the Unicode case-folding rules embedded in JavaScript:
output = input.toLowerCase()| Operation | Description |
|---|---|
| toLowerCase | Locale-aware Unicode lowercase mapping |
| char count | Number of code points in the input |
| word count | Whitespace-delimited tokens |
Assumptions and Limits
The Uppercase to Lowercase Converter respects Unicode but does not perform locale-specific folding such as Turkish dotted-I behaviour beyond what the browser provides. For special locale handling, use a dedicated library.
