+ * Converts a string to upper case.
+ *
+ * Upper case is the naming convention in which each word is written in uppercase and separated by an space ( ) character.
+ *
+ * @param {string} str - The string that is to be changed to upper case.
+ * @returns {string} - The converted string to upper case.
+ *
+ * @example
+ * const convertedStr1 = upperCase('camelCase') // returns 'CAMEL CASE'
+ * const convertedStr2 = upperCase('some whitespace') // returns 'SOME WHITESPACE'
+ * const convertedStr3 = upperCase('hyphen-text') // returns 'HYPHEN TEXT'
+ * const convertedStr4 = upperCase('HTTPRequest') // returns 'HTTP REQUEST'
