npm install @compwright/is-upper-case[![Build status][travis-image]][travis-url]
Check if a string is upper case.
Forked from blakeembrey/is-upper-case, with the following improvements:
* Removed unnecessary dependencies
* Added locale support
``
npm install @compwright/is-upper-case --save
`javascript
const isUpperCase = require('@compwright/is-upper-case')
isUpperCase('STRING') // true
isUpperCase('String') // false
isUpperCase('string') // false
// Returns undefined for non-strings
isUpperCase(null) // undefined
`
Locale support:
`javascript``
isUpperCase('STRİNG', 'tr') // true
Includes a TypeScript definition.
