How to use Object.keys() In Typescript

Using Object.entries()

This approach involves using the Object.keys() method to extract all the keys of the object and then checking the length of the resulting array.

Example: In this example, we create an empty object `myObject` and then use the `Object.keys()` method to check if it is empty.

Javascript


                    const obj1: Record<string, any> = {};
const obj2: Record<string, any> =
  { name: "John", age: 30 };

if (Object.keys(obj1).length === 0) {
  console.log('obj1 is empty'); 
} else {
  console.log('obj1 is not empty');
}

if (Object.keys(obj2).length === 0) {
  console.log('obj2 is empty');
} else {
  console.log('obj2 is not empty'); 
}

Output:

obj1 is empty
obj2 is not empty
