    The issue in the given code lies within the for loop condition. The loop will never execute because the condition i == word.length is not met initially. The loop should run as long as i is less than word.length, not when it is equal to it.

    To correct the code, you should change the for loop condition from i == word.length to i < word.length

    Your for loop is wrong. Correct it as :

    for(let i=0; i < word.length; i++) { }

    function letterFinder(word,match){
   for(let i=0; i < word.length; i++){
      if(word[i]==match){
        console.log('Found the', match, 'at', i);
      }
      else{
        console.log('---No match found at',i);
      }
   }
}
word="test";
letter="t";
console.log(letterFinder(word,letter))
