how to check if an object is empty in node code example

Example 1: javascript test for empty object

// because Object.entries(new Date()).length === 0;
// we have to do some additional check
Object.entries(obj).length === 0 && obj.constructor === Object

if (typeof value !== 'undefined' && value) {
    //deal with value'
};
