Quote from MDN: `However, this API has been deprecated and removed from browsers. You can use the more general Proxy object instead.` – Shilly Apr 27 '17 at 10:24

As stated in the mdn documentation : https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/observe
The Object.observe() method was used for asynchronously observing the changes to an object. It provided a stream of changes in the order in which they occur. However, this API has been deprecated and removed from browsers. You can use the more general Proxy object instead.

you can achieve this with getters and setters and alternatively, in a browser with support for Proxies, you can write a more generic solution. Check here

2The issue is that you have to plug into the object chain. There is no way to observe changes in a "readymade" object that is parsed from JSON for example.. – Julian F. Weinert Oct 12 '20 at 19:24

Implementing this in getters and setters is a lot of boilerplate or 'monkey coding' which leaves technical debt and 'too much code' issues (=more time, more bugs, more time to read, more cost, no more value [than an alternative]). It is a subtle and often unnoticed thief of IT budget. – FastAl Feb 21 '23 at 04:39
