Checking if object is empty for Angular 4

if( obj[0] )

1	if( obj[0] )

a cleaner version of this might be:

if( typeof Object.keys(obj)[0] === 'undefined' )

1	if( typeof Object.keys(obj)[0] === 'undefined' )

where the result will be undefined if no object property is set.

if( Object.keys(obj).length &gt; 0 )

1	if( Object.keys(obj).length > 0 )

as an extra option.

if( data instanceof Array )

1	if( data instanceof Array )

if( data instanceof Object )

1	if( data instanceof Object )
