Usage

Once installed, you can import the methods to use them in your project.

const { findNumber, findLetter } = require('numalpha');

// Find the position of a letter
console.log(findNumber('a')); // Outputs: 1
console.log(findNumber('z')); // Outputs: 26
console.log(findNumber('!')); // Outputs: 0 (invalid letter)

// Find the letter by position
console.log(findLetter(1)); // Outputs: 'a'
console.log(findLetter(26)); // Outputs: 'z'

// Error handling
try {
    console.log(findLetter(0)); // Throws an error
} catch (error) {
    console.error(error.message); // Outputs: The number must be between 1 and 26! Try again
