The default export of this module is a constructor wrapping the given string in an object. Produce the given string by calling the property named "str". Methods for manipulating the given string are as follows.
You can make a string from an array, stringify a number of seconds into H:MM:SS format, stringify a number of seconds into machine-readable format "##H ##M ##S", stringify a number of seconds into a valid duration string for the "datetime" attribute of the semantic time tag, of the form "PT##H##M##S", according to the HTML Standard
You can validate that the value given to constructor is a string, verify that the string of the object contains a substring and multiple occurrences, verify that the string of the object begins with any alphabetic or capital alphabetic character, break up the string of the object into a multi-line string with no more than 79 printed characters per line, and show the result of growing a CSV by one value.
