JavaScript JavaScript and the DOM (Retiring) Getting a Handle on the DOM Select a Page Element By Its ID

Why does my code almost never work even though it looks the same as shown in the video?

Here is my Javascript: ```const myHeading = document.getElementById('myHeading'); const myButton = document.getElementById('myButton'); const myTextInput = document.getElementByID('myTextInput');

myButton.addEventListener('click', () => { myHeading.style.color ='red';


Here is the HTML:
```<!DOCTYPE html>
    <title>JavaScript and the DOM</title>
    <link rel="stylesheet" href="css/style.css">

    <h1 id="myHeading">JavaScript and the DOM</h1>
    <p>Making a web page interactive</p>
       <input type ="text" id="myTextInput"> 
    <button id="myButton">Change the color to whatever you like</button>
    <script src="app.js"></script>

You're getting a TypeError because :

const myTextInput = document.getElementByID('myTextInput');

.getElementById is case-sensitive and you've got a capital D in "Id",

Wild Porpoise,

It looks like you capitalized "ID" in document.getElementByID('myTextInput') Try: document.getElementById('myTextInput')

Give that a shot and see what happens. Best of luck!
