Move Property
Move a property from one object to another object.
Usage
var moveProperty = require( '@stdlib/utils/move-property' );
moveProperty( source, prop, target )
Moves a property from one object
to another object
.
var obj1 = {
'a': 'b'
};
var obj2 = {};
var bool = moveProperty( obj1, 'a', obj2 );
// returns true
If the operation is successful, the function returns true
; otherwise, false
.
var obj1 = {
'a': 'b'
};
var obj2 = {};
var bool = moveProperty( obj1, 'c', obj2 );
// returns false
Notes
-
A transfer is shallow.
var arr = [ 1, 2, 3 ]; var obj1 = { 'a': arr }; var obj2 = {}; var bool = moveProperty( obj1, 'a', obj2 ); console.log( obj2.a === arr ); // => true
-
The property is deleted from the source
object
. -
The property's descriptor is preserved during transfer.
-
If a source property is not
configurable
, the function throws anError
, as the property cannot be deleted from the sourceobject
.
Examples
var moveProperty = require( '@stdlib/utils/move-property' );
var obj1 = {
'beep': 'boop'
};
var obj2 = {
'foo': 'bar'
};
var bool = moveProperty( obj1, 'beep', obj2 );
if ( bool === false ) {
console.log( 'failed to move property' );
}
console.dir( obj1 );
/* =>
{}
*/
console.dir( obj2 );
/* =>
{
'foo': 'bar',
'beep': 'boop'
}
*/
