Are you looking to convert a JavaScript object to an underscored object? With just a few simple steps, you can easily achieve this conversion. Follow the steps below to convert your 'u' to 'obj' effortlessly:

1. Create a JavaScript Object: First, start by creating a JavaScript object with the key-value pairs that you want to convert to an underscored format.

2. Use the Underscore Library: The Underscore library provides a range of utility functions for common programming tasks, including object manipulation. You can utilize the `_.mapObject` function to convert the keys of the JavaScript object to an underscored format.

3. Perform the Conversion: Once you have access to the Underscore library, simply use the `_.mapObject` function to perform the conversion. Pass in the JavaScript object and a custom mapping function that transforms the keys to an underscored format.

4. Obtain the Underscored Object: After performing the conversion, you will obtain the underscored object with the keys transformed to the desired format. You can now use this underscored object as needed in your code.

By following these four simple steps, you can effortlessly convert a JavaScript object to an underscored object. This conversion can be particularly useful when working with various data structures or when interacting with APIs that require underscored keys.
