javascript check if object is not empty

Comment

// ECMA 5+
// because Object.keys(new Date()).length === 0;
// we have to do some additional check
obj // 👈 null and undefined check
&& Object.keys(obj).length === 0
&& Object.getPrototypeOf(obj) === Object.prototype

// Note, though, that this creates an unnecessary array (the return value of keys).

check object is null empty or undefined

Comment

function isRealValue(obj)
{
 return obj && obj !== 'null' && obj !== 'undefined';
}

//Use isRealValue(obj) to check further, will always return truthy object.
