Explanation :- a user gives a String (it can be incomplete uppercase or

partial uppercase) and then the program would convert it into a

complete(all characters in lower case) lower case string. The

logic we have used in the following program is: All the upper case

characters (A-Z) has ASCII value ranging from 65 to 90 and their

corresponding lower case characters (a-z) have ASCII values 32

greater than them. For example ‘A‘ has an ASCII value of 65

and ‘a‘ has an ASCII value of 97 (65+32). The same applies to other

characters.

/**

* LowerCaseConversion takes any case-style string and converts it to the lower case-style string.

* @param {String} inputString any case style string

* @returns {String} lower case string

const LowerCaseConversion = (inputString) => {

// Take a string and split it into characters.

const newString = inputString.split('').map((char) => {

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

const presentCharCode = char.charCodeAt()

// If the character code lies between 65 to 90 it means they are in the upper case 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

})

// After modification, with the help of the join method, join all the characters and return them.

return newString.join('')

}

export { LowerCaseConversion }
