javascript - compare 2 strings with the same length-CodePudding

I'm making a word guessing application(like Wordle).
Let's assume I have a predefined word

let predefinedWord = "apple";

I want to make a function to compare with the predefined word.

const compare = (word) => {
  // compare the guess with the predefined word apple
}

let myGuess = "alley"
const result = compare(myGuess); // compare apple with alley
// return 
// ["Matched", "Included", "Included", "Included", "Not Matched"]

How can I make the function like this?

If the word length is as short as in wordle, a direct approach works well:

let predefinedWord = "apple";
let predefArr = predefinedWord.split('');


const compare = (predef,word) => {
  return word
         .split('')
         .map( (letter,i) => {
           if (predef[i] === letter) return "Matched";
           if (predef.includes(letter)) return "Included";
           return "Not Matched"
         });
  
}

let myGuess = "alley"
const result = compare(predefArr, myGuess); // compare apple with alley
// return 
// ["Matched", "Included", "Included", "Included", "Not Matched"]

console.log(result)

const compare = (word) => {
  let result = [];
  for(let i=0;i<word.length;i  ){
    if(predefinedWord.includes(word[i])){
      result.push(predefinedWord.indexOf(word[i]) === i?"Matched":"Included")
    }else{
      result.push("Not Matched")
    }
  }
  return result;
}
