Q127. test for an empty object: user-defined constructors about javascript-interview-questions HOT 4 CLOSED

Thank you. We don't write questions about lodash. The first thread in this post is not related to date objects . Please create a PR with a clear answer for any question.

from javascript-interview-questions.

Lodash does the task well:

_ = require('lodash')
console.log('lodash: new MyBox():', _.isEmpty(new MyBox()));
console.log("lodash: new MyBox('tv'):", _.isEmpty(new MyBox('tv')));

Result:

lodash: new MyBox(): true
lodash: new MyBox('tv'): false

from javascript-interview-questions.

lodash handles Dates too:

console.log('new Date():', isEmpty(new Date()));
console.log('lodash: new Date():', isEmpty(new Date()));

Result:

new Date(): false
lodash: new Date(): false

@sudheerj, why close an issue if answer isn't correct?

See example after "it doesn't process objects created with user-defined constructors" above.

Lodash source code can be used as reference for hand-written implementation, I just gave a hint.
