This check marks variable names that have not been written in camelCase. In camelCase names are written without any punctuation, the start of each new word being marked by a capital letter. Thus the name database connection string becomes `databaseConnectionString`. Loading history...

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.
