how to check json object is empty or not in javascript code example

Example 1: javascript check if object is empty

function isObjectEmpty(obj) {
    return Object.keys(obj).length === 0;
}

Example 2: 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

Example 3: how to check if a json object is empty

obj.length() == 0
is what I would do.
