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)object check null or empty
Object.entries(obj).length === 0 && obj.constructor === Objectcheck if object values are empty
const isEmpty = !Object.values(object).some(x => x !== null && x !== '');Copyright © 2021 Codeinu
