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.

const titleCaseConversion = (inputString) => {

if (inputString === '') return ''

// Extract all space separated string.

const stringCollections = inputString.split(' ').map(word => {

let firstChar = ''

// Get the [ASCII](https://en.wikipedia.org/wiki/ASCII) character code by the use charCodeAt method.

const firstCharCode = word[0].charCodeAt()

// If the ASCII character code lies between 97 to 122 it means they are in the lowercase so convert it.

if (firstCharCode >= 97 && firstCharCode <= 122) {

// Convert the case by use of the above explanation.

firstChar += String.fromCharCode(firstCharCode - 32)

} else {

// Else store the characters without any modification.

firstChar += word[0]

}

const newWordChar = word.slice(1).split('').map(char => {

// Get the ASCII character code by the use charCodeAt method.

const presentCharCode = char.charCodeAt()

// If the ASCII character code lies between 65 to 90, it means they are in the uppercase so convert it.

if (presentCharCode >= 65 && presentCharCode <= 90) {

// Convert the case by use of the above explanation.

return String.fromCharCode(presentCharCode + 32)

}

// Else return the characters without any modification.

return char

})

// Return the first converted character and remaining character string.

return firstChar + newWordChar.join('')

})

// Convert all words in a string and return it.

return stringCollections.join(' ')

}

export { titleCaseConversion }
