Dual Words

I was bored and made this small tool to merge words together, below is an example of it working in action

This was made using this

If you want to make a word with the allowed letters, this tool can help. The allowed letters are: "aeioucdhmrtvx"

Alphabet.js

export default class Alphabet {
    static generate(lowercase = true){
        let start = lowercase ? 97 : 65;
        return new Array(26).fill(1).map((_, i) => String.fromCharCode(start + i));
    }
    
    static get lowercase(){
        return this.generate(true);
    }
    
    static get uppercase(){
        return this.generate(false);
    }
    
    static get combined(){
        return this.lowercase.concat(this.uppercase);
    }
    
    static get combiningSmallLetters(){
        return {
            // Vowels
            a: 'ͣ ',
            e: 'ͤ ',
            i: 'ͥ ',
            o: 'ͦ ',
            u: 'ͧ ',

            // Consonants
            c: 'ͨ ',
            d: 'ͩ ',
            h: 'ͪ ',
            m: 'ͫ ',
            r: 'ͬ ',
            t: 'ͭ ',

        };
    }

combineWords.js

export default function combineWords = (w1, w2) => {

    w2 = w2.split('');
    let illegal = 0;
    
    return w1.reduce((total, original, position) => {
        let index = Alphabet.combined.findIndex(item => item === original);
        
        if(index === -1){
            illegal++;
            return total += original;
        }
      
        let character = w2[position - illegal];
        
        if(character){
            let found = Alphabet.combiningSmallLetters[character.toLowerCase()];
            
            if(found){
                let combined = [
                    String.fromCodePoint(original.charCodeAt(0)),
                    String.fromCodePoint(found.charCodeAt(0)),
                    // Turns out you can put these characters ontop of each other!
                    // ... infinitely
                    // String.fromCodePoint(found.charCodeAt(0)),
                ].join('');

                return total += combined.normalize('NFC');
            }
        }
        
        return total += original;
    }, '');
