When new image is created, image.width returns 0
The code below says that spike.image.width = 0. Why is this? I'm probably missing something that is obvious.
spike.image.width = 0
class Spike {
constructor(x = 200, y = 200) {
this.x = x;
this.y = y;
this.image = new Image();
this.image.src = "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSIBO-v6hQoEBhzmZ05mKzgYqrsZ0svgsED7IDR4dIVNxc78uc2";
}
}
const ctx = document.getElementById("canvas").getContext("2d");
const spike = new Spike;
console.log(spike.image.width);
<!DOCTYPE html>

<canvas id="canvas" width="400" height="600"></canvas>
<script src="js/main.js"></script>

When the console.log fires, the image hasn't fully loaded yet. You have to check for when the image has loaded
console.log
const spike = new Spike;
spike.image.onload = function()
{
console.log(spike.image.width);
}
