JavaScript Check Object Is Empty

Feb 22, 2021
Object.keys({}).length == 0 // true

If the object could be null

if (obj && Object.keys(obj).length == 0) {  console.log('object is empty')}

If the variable is a non-object, the check will return true

Object.keys(123).length == 0  // true

You might want to try _.isEmpty(obj)

_.isEmpty({name: 'Desmond'})  // false_.isEmpty({})   // true_.isEmpty(null) // true_.isEmpty(123)  // true
