Utilizing a blank object as an argument for a conditional if statement in a loop

I've been attempting something along these lines,

const myObject = {};
if(myObject){
//perform an action
}

My goal is for the condition to be false when the object is null.

I attempted using JSON.stringify(myObject) but it still contains curly braces '{}.'

Answer №1

To determine the length of the array of own keys in an object, you can utilize the Object.keys method.

function checkKeys(obj) {
    if (Object.keys(obj).length) {
        console.log(obj.name);
    }
}

var person = {};

checkKeys(person);
person.name = 'Alice';
checkKeys(person);

Answer №2

To determine if an object is empty, meaning it has no properties, you can use the following code:

Object.keys(obj).length === 0

Object.keys() will return all properties of the object in an array.

If the length of the array is zero (.length === 0), then the object can be considered empty.

Answer №3

To determine if an object is empty, you can utilize the Object.keys(myObj).length method to calculate its length.

Here is a practical example:

    var myObj = {};
    if(Object.keys(myObj).length>0){
      // This section will not be executed
      console.log("hello");
    }

    myObj.test = 'test';

    if(Object.keys(myObj).length>0){
      console.log("This section will be executed");
    } 
For more information about Object.keys, refer to the official documentation on MDN.
