Name causes undefined

[aquacash5]

I was playing with the library. It works amazingly well for how simple it is. However, when I used the name João it returned undefined.

var nc = require('namecase')

String.prototype.toNameCase = function () {
  var name = this.toString()

  if (nc.checkName(name)) {
    return nc(name, { individualFields : true } )
  }
}

console.log("João".toNameCase())
// returns undefined

Never mind, the issue was with my use of the example toNameCase function.
