How to check if a specific object is empty in TypeScript?
To check if specific object is empty in TypeScript, we can use the Object.keys method.
For instance, we write
class Brand {}
const brand = new Brand();
if (Object.keys(brand).length === 0) {
console.log("No properties");
}
to check if the brand object is empty with Object.keys(brand).length === 0.
Object.keys returns an array of non-inherited string keys in brand.
So if the returned array’s length is 0, then it’s empty.
Conclusion
To check if specific object is empty in TypeScript, we can use the Object.keys method.
