find the middle letter of an odd word in the middle of the middle word of a sentence. my code just returns undefined not sure why. is there a better method?

 if (string.length%2===1){
  
 const newArray = string.split(" ")
    const middleWord = newArray[(newArray.length+1)/2];
    
    if (middleWord.length%2===1){
      return middleWord[(middleWord.length+1)/2];
    }
    console.log(middleWord[(middleWord.length+1)/2])
    else {
        const firstmiddleletter = middleWord[middleWord.length/2];
      const secondmiddleletter = middleWord[(middleWord.length/2)+1];
      const middletwo = `${firstmiddleletter}${secondmiddleletter}`;
      console.log(middletwo)
 
      return middletwo;
    }
    return 1;
     
  }
  
 // console.log(middleWord)
  
}

const stringy = "I want to see the middle letter of the middle word";
//console.log((middle(stringy)))

could you please give all your code? It seems the function definition is missing and makes debugging difficult
