Every so often I discover a property in JavaScript objects that I didn’t know existed, oftentimes using another trick to accomplish the same functionality. One such property I just learned about was isConnected, a node property that attached to a context (i.e. document).
Here’s how to use Node.prototype.isConnected:
const el = document.createElement('div');
el.isConnected; // false
document.body.appendChild(el);
el.isConnected; // true
I used to run parentNode checks on the element to see if it had been injected but that’s not always accurate, so I’m glad isConnected exists!
