delete operator will do your job.
delete operator delete property of object.
var obj = {
accessKey : "" ,
length : 2 ,
selector : ".nav"
}
delete obj.selector ; // return true and remove object property.
[code]
delete obj.selector
will remove selector property of obj(object)
you can also use like :: delete(syntax)
[code]
delete (obj.selector) // return true and remove object property.
when delete operator return true . it means property got deleted. if delete operator return false means property is not deleted.
var d=1;
delete d ; // return false .
