{{alias}}( obj )
|
||
|
|
Returns an array of an object's own enumerable property names which are not
|
||
|
|
integer indices.
|
||
|
|
|
||
|
|
Name order is not guaranteed, as object key enumeration is not specified
|
||
|
|
according to the ECMAScript specification. In practice, however, most
|
||
|
|
engines use insertion order to sort an object's keys, thus allowing for
|
||
|
|
deterministic extraction.
|
||
|
|
|
||
|
|
If provided `null` or `undefined`, the function returns an empty array.
