Problem statement and Explanation : https://www.codeproject.com/Tips/162540/Letter-Case-Conversion-Algorithms-Title-Case-Toggl.
|
|
[Title case](https://en.wikipedia.org/wiki/Title_case) is a style where all words are capitalized. Officially, title case
|
|
does not capitalize some words, such as very short words like "a" or "is", but for the purposes of this function, a general approach
|
|
is taken where all words are capitalized regardless of length.
|

/**
|
|
* The titleCaseConversion function converts a string into a title case string.
|
|
* @param {string} inputString The input string which can have any types of letter casing.
|
|
* @returns {string} A string that is in title case.
