Upper case a string.
Supports Unicode (non-ASCII characters) and non-string entities, such as objects with a toString
property, numbers and booleans. Empty values (null
and undefined
) will result in an empty string.
npm install upper-case --save
var upperCase = require('upper-case') upperCase(null) //=> "" upperCase('string') //=> "STRING" upperCase('string', 'tr') //=> "STRÄ°NG" upperCase({ toString: function () { return 'test' } }) //=> "TEST"
Includes a TypeScript definition.
