Full Stack JavaScript Techdegree Student 12,309 PointsWhy does my code run without any error, despite not having followed the coding instruction
Hi everyone,
I am following the video, but I code first and then look at the solution. I coded the following in my JS file:-
const myHeading = document.getElementById('myHeading');
myButton.addEventListener('click', () => {
myHeading.style.color = 'tomato';
})
Link to the screenshot of the workspace ====>>> https://w.trhou.se/4wjejz3b8a
The code ran without any error, and did exactly what it was meant to do, i.e change the color of myHeading to 'tomato'.
The problem with the code is that, I have not extracted myButton from the DOM, and it still gets the element and manipulate it.
Can someone please shed some light on how that happened?
Thanks again. Cheers!!!
