Lower case the first character of 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 lower-case-first --save
var lowerCaseFirst = require('lower-case-first')
lowerCaseFirst(null) //=> ""
lowerCaseFirst('STRING') //=> "sTRING"
Includes a TypeScript definition.
