需要這個詞的解釋guessing javascript

Question

所以，我想檢查我輸入的輸入是否正確執行，但爲什麼if語句總是返回false，即使我給出正確的輸入？ 我不想要解決方案只需要解釋。請問有誰能解釋？我已經包含了我的html輸入元素，以防萬一出錯。

<script> 

    var text1 = ["O","K","E"]; 
    var text2 = ["_","_","_"]; 

    function guess(j){ 
     for(i=0; i < text1.length; i++){ 
      if(j == text1[i]){ 
       text2[i] = j; 
       console.log(text2[i]) 
      } 
      else { 
        console.log("try again") 
      } 
     } 
    } 
</script>

的@Unglückspilz在代碼中的註釋：

// extra "K" to show how to handle multiple finds 
var text1 = ["O","K","E","K"]; 
var text2 = ["_","_","_","_"]; 

function guess(j){ 
    // a flag to set if one or more letters were found 
    found = false; 
    // check every letter in the haystack against given needle 
    for(i=0; i < text1.length; i++){ 
     if(j == text1[i]){ 
      // exchange underbar against found letter(s) 
      text2[i] = j; 
      console.log(text2[i]); 
      // set flag to true 
      found = true; 
     } 
    } 
    // no letter was correct 
    if(!found){ 
     console.log("try again"); 
    } 
    // return boolean if anything was found (but not how many) 
    return found; 
}
