When working with JavaScript, you often need to inspect the contents of objects to understand their structure and values. Here are some effective ways to print the content of a JavaScript object:

Using console.log()
The most common and straightforward method to print a JavaScript object is using console.log().

This will print the object to the browser's console in a readable format.

Using JSON.stringify()
If you need a more structured and readable format, especially for complex or nested objects, JSON.stringify() is useful.

The second argument in JSON.stringify can be used to filter out properties, and the third argument specifies the number of spaces to use for indentation, making the output more readable.

Using console.table()
For tabular data, console.table() provides a clear, tabular representation.

This prints the array of objects in a table format in the console, which can be particularly useful for arrays of objects.

Iterating with for...in
For a more customized approach, you can iterate over the object's properties using a for...in loop.
