A friendly. Improved implementation of object. Prototype. tostring

Almost every object in Javascript has a tostring () method, which is built-in and used to output the current
Variable information. But for the most common object objects, Every time tostring is used, [object] is printed.
{A: 1, B: 2, C: 3}. tostring () ==> [object]
This is depressing, so I have implemented a friendly function that prints all the members of the object,
Nested output is supported, and array content can be printed in a friendly way.
Post it here CodeWe hope to learn and improve this function together.
