Confused when I tried

var buttons = document.getElementsByTagName('button');

function createHandler(name) {

console.log(name);

}

for(var i = 0; i < buttons.length; i += 1) { var button = buttons[i]; var buttonName = button.innerHTML; button.addEventListener('click', createHandler(buttonName)); }

//for the last solution I deleted the return function from the createHandler, now without clicking the buttons the console is giving answer. Can anyone help me?

You forgot to wrap console.log in an anonymous function:

function createHandler(name) {
  return function() {
    console.log(name);
  }
}
