Checks if a string contains only alphabetic characters.

• Use RegExp.prototype.test() to check if the input string matches against the alphabetic regexp pattern.

const isAlphabetOnly = input => /^[a-zA-Z]*$/.test(input)

isAlphabetOnly('sampleInput'); // true
isAlphabetOnly('this Will fail'); // false
isAlphabetOnly('123'); // false
