Subject: [PATCH] bug fix - combined mapped arg with blank string

combined x.toString() result with blank string to avoid exception in case x is invalid/undefined, failing to call toString()

let s = args.map(x => x.toString()).join(' ');
                              ^
TypeError: Cannot read properties of undefined (reading 'toString')
