How to remove all blank Objects from an Object in Javascript?

How to remove all blank Objects from an Object in Javascript? Like this

const test={a:'a',b:{},c:{c:{}}}

How to get result:

test={a:'a'}

Answer*

Here is another way with some details.
## Needs/To keep in mind:
1. **getting within obj** implies looping
2. **identify objects**: avoid element not being [object typed and only checks for object typed][1]
3. **going deeper**: for nested objects, a [recursive pattern][2] is handy. 
*( careful to avoid infinite loop w/ recursive function execution )*
4. **delete/remove obj if empty** 

## Code snippet:




 const test = {
 a: "a", b: {},
 c: { c: {} },
 d: {
 d: { e: {} }
 },
 }

 function checkObjEmptiness(obj) {
 // increases readability
 // avoid "typeof" checking as "typeof [] === 'object' // returns true"
 
 let isObject = (x) => x && x instanceof Object, 
 isEmpty = (x) => x && !Object.keys(x).length;


 // 1. loops over obj to check each elements emptiness
 for (let k in obj) {
 // 2. check for object within object based on: isObject && !isEmpty
 // 3. if object and not empty --> re-apply processus
 if (isObject(obj[k]) && !isEmpty(obj[k])) checkObjEmptiness(obj[k]);

 // handles deletion on obj if empty [ or value if empty ]
 //if (isEmpty(obj[k]) || !obj[k]) delete obj[k]; // handles empty values

 // 4. deletes object if empty
 if (isEmpty(obj[k])) delete obj[k]; //handles empty object
 }
 return obj;
 }

 checkObjEmptiness( test )

How to Format

create code fences with backticks ` or tildes ~
```
like so
```
add language identifier to highlight code
```python
def function(foo):
print(foo)
```
put returns between paragraphs
for linebreak add 2 spaces at end
_italic_ or **bold**
indent code by 4 spaces
backtick escapes `like _so_`
quote by placing > at start of line
to make links (use https whenever possible)

<https://example.com>

[example](https://example.com)

<a href="https://example.com">example</a>

How to Tag

A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.

complete the sentence: my question is about...
use tags that describe things or concepts that are essential, not incidental to your question
favor using existing popular tags
read the descriptions that appear below the tag

If your question is primarily about a topic for which you can't find a tag:

combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
