Create span element in li with Javascript

Question

I'm working on a to-do list project and when creating a new li I would like it to start with a span containing a "X". I wrote the code below, but instead of a span I get "[object HTMLSpanElement]". Anybody knows how to fix this? Thank you!

var enterItem = document.querySelectorAll("input");
var todoList = document.getElementById("todo-list");

for (var i = 0; i < enterItem.length; i++) {
  enterItem[i].addEventListener("keypress", function(key) {
    if(key.which === 13){

      var newLi = document.createElement("li");
      var span = document.createElement("span");
      var newItem = this.value;

      span.textContent = "X";
      newLi.appendChild(document.createTextNode(span + " " + newItem));
      todoList.appendChild(newLi);
      this.value = "";
    }
  });
}

You are trying to add an html element in a textNode so it triggers the toString of the element

You need

 const todoList = document.getElementById("todo-list"); document.getElementById("inputContainer").addEventListener("keypress", function(e) { const tgt = e.target; if (tgt.type === "text" && e.which === 13) { let newLi = document.createElement("li"); let span = document.createElement("span"); span.classList.add("remove"); let newItem = tgt.value; span.textContent = "X"; newLi.appendChild(span) newLi.appendChild(document.createTextNode(" " + newItem)); todoList.appendChild(newLi); tgt.value = ""; } }); document.getElementById("todo-list").addEventListener("click", function(e) { const tgt = e.target; if (tgt.classList.contains("remove")) { tgt.closest("li").remove(); } })

 <div id="inputContainer"> <input type="text" /> </div> <ul id="todo-list"></ul>
