how find empty object in js

const emptyObject = {}

Object.entries(objectToCheck)
If it returns an empty array, it means the object does not have any enumerable property,
which in turn means it is empty.

Object.entries(objectToCheck).length === 0

Lodash, a popular library, makes it simpler by providing the isEmpty() function:
_.isEmpty(objectToCheck)
