Tutorial: Changing property names

Here below is an example on changing a property name.

    
    var Scrubber = require('object-scrubber');
        
    var testObj = { }            
    var scrubber = new Scrubber()

    scrubber.when(function (x) {
        return x.parent && x.key === '_id'
    }, function (x) {
        // set the value to a new property in the parent
        x.parent.id = x.value
        // delete the previous property
        delete x.parent._id
        // change to the new key for the next processors to find 
        x.key = 'id'
        // scrub the new value for other processors to process
        return x.scrub(x.parent.id)
    });

    scrubber.scrub(testObj);
