error handling - I can't seem to figure out how to fix two lints in my javascript. Can someone help me understand? -

i started javascript , made first game today! happy , in process of making lint free.

i'm getting frustrated, fixed mistakes(lints) there 2 can't seem fix! i've been trying on hour. please me solve this? i'm getting frustrated :(

the lints are:

5 'prompt' used before defined. var name = prompt("hallo speler, wat uw naam?.", "naam van speler");

5 expected identifier , instead saw '"'. var name = prompt("hallo speler, wat uw naam?.", "naam van speler");

this javascript code:

//schrijft functie begin spel. value van de input wordt een string. opnieuw knop wordt disabled.        var name = prompt("hallo speler, wat uw naam?.", "naam van speler");    var data = [          [0, 11, "een hele goede morgen,"],          [12, 17, "goede middag,"],          [18, 24, "goede avond"]      ],      hr = new date().gethours();    (var = 0; < data.length; i++) {      if (hr >= data[i][0] && hr <= data[i][1]) {          document.getelementbyid('welkom').innerhtml = data[i][2] + " " + name;      }  }      function beginspel() {            document.getelementbyid("input_txt").value = "";        document.getelementbyid("input_txt").focus();        document.getelementbyid("input_txt").disabled = false;      document.getelementbyid("guess_btn").disabled = false;      document.getelementbyid("playagain_btn").disabled = true;        //tekst weergeeft op het begin informatie on wat je moet doen.      document.getelementbyid("message_txt").innerhtml = "kies een nummer tussen 1 en 100.";        //nummer van de computer wordt berekend.       randomnumber = math.ceil(math.random() * 100);        //variabele input de tekst van input_txt      input = document.getelementbyid("input_txt");          var clicks = 0; // sets global variable      // when window loads        document.getelementbyid("guess_btn").addeventlistener("click", function() {          //the above creates event listener tell          //script when clicks on element          //with id "button"            clicks++; // adds 1 variable clicks          document.getelementbyid('aantalklik').innerhtml = "u heeft " + clicks + " keer geraden!"; // displays clicks popup      })        }        var guess_btn = document.getelementbyid('guess_btn');  guess_btn.addeventlistener('click', guessnumber);    var playagain_btn = document.getelementbyid('playagain_btn');  playagain_btn.addeventlistener('click', beginspel);          function guessnumber() {     guess = document.getelementbyid("input_txt").value;        document.getelementbyid("input_txt").focus();              if (guess === "") {          document.getelementbyid("message_txt").innerhtml = "0 te laag. probeer opnieuw!";      } else if (guess > randomnumber) {          document.getelementbyid("message_txt").innerhtml = guess + " te hoog. probeer opnieuw!";          input_txt.value = "";      } else if (guess < randomnumber) {          document.getelementbyid("message_txt").innerhtml = guess + " te laag. probeer opnieuw!"          input_txt.value = "";      } else {          document.getelementbyid("message_txt").innerhtml = "je hebt goed geraden! het nummer " + guess + ".";          input_txt.value = "";                  endgame();      }      }    function endgame() {      document.getelementbyid("input_txt").disabled = true;      document.getelementbyid("guess_btn").disabled = true;      document.getelementbyid("playagain_btn").disabled = false;  }    window.onload = beginspel;

the first error because not know prompt defined. can prefix window this: window.prompt(...

or add prompt list of "globals" passed in jshint configuration: http://jshint.com/docs/
