## Why Do Chrome & Safari Console Logs Display JavaScript Objects Differently From Firefox?

JavaScript Object Display Discrepancy in Console Logs

When displaying JavaScript objects in console logs, users have encountered varying results across Firefox, Chrome, and Safari browsers. While Firefox's Firebug accurately reflects changes made to object attributes, Chrome and Safari console logs exhibit a peculiar behavior.

In Chrome's console, console.log calls involving objects create a reference to the object. Until the object tab is opened in the console, the reference remains live and reflects any changes made to the object. However, once the object tab is opened, the logged object becomes "cached" and displays the most recent updated value regardless of further modifications to the original object.

This behavior, stemming from a design decision by the Chromium team, is not considered a bug. However, it can be inconvenient for developers who rely on accurate object display in console logs.

To work around this issue, there are several options available. Developers can choose to log a non-object value of the object, such as a serialized representation obtained using JSON.stringify(foo). This will provide the most up-to-date representation of the object's state.
