Package Exports
- match-casing
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (match-casing) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

matchCasing(value, base)
Parameters
value(string) — Value whose case to change.match(string) — Value whose case to match.
Returns
string — value, but cased as base.
Algorithm
- If
baseis uppercase,valueis uppercased; - Else, if
baseis lowercase,valueis lowercased; - Else, if the first alphabetic character in
baseis uppercase, and the rest ofbaseis lowercase, uppercase the first alphabetic character invalueand lowercase the rest. - Else, return
valueunmodified.
The third case, where value takes on a capitalised, deals with
initial non-alphabetical characters as expected.
