Object.watch() and Object.Observe were once valuable tools for tracking object modifications. However, they are now deprecated and require viable alternatives.
One viable option is a jQuery plugin. However, there may be better cross-browser solutions.
One effective cross-browser alternative is a JavaScript shim library. It provides a consistent Object.watch() implementation across browsers.
Here's an example of how to use the shim library:
<code class="javascript">var options = {'status': 'no status'}, watcher = createWatcher(options); watcher.watch("status", function(prop, oldValue, newValue) { console.log("old: " + oldValue + ", new: " + newValue); return newValue; }); watcher.status = 'asdf'; watcher.status = '1234'; console.log(watcher.status);</code>
