Read-Write Accessor
Define a read-write accessor.
Usage
var setReadWriteAccessor = require( '@stdlib/utils/define-read-write-accessor' );
setReadWriteAccessor( obj, prop, getter, setter )
Defines a read-write accessor.
var word = 'bar';
var obj = {};
function getter() {
return word + ' foo';
}
function setter( v ) {
word = v;
}
setReadWriteAccessor( obj, 'foo', getter, setter );
var v = obj.foo;
// returns 'bar foo'
obj.foo = 'beep';
v = obj.foo;
// returns 'beep foo'
Notes
- Read-write accessors are enumerable and non-configurable.
Examples
var setReadWriteAccessor = require( '@stdlib/utils/define-read-write-accessor' );
function Foo( name ) {
if ( !(this instanceof Foo) ) {
return new Foo( name );
}
setReadWriteAccessor( this, 'name', getName, setName );
return this;
function getName() {
return 'Hello, ' + name;
}
function setName( v ) {
name = v;
}
}
var foo = new Foo( 'Grace' );
console.log( foo.name );
foo.name = 'Ada';
console.log( foo.name );
