copy(src).withAccess().and(other).to(des);

Example

var copy = require('copy-to');

var src = {
  _name: 'foo',
  set name(val) {
    this._name = val;
  },
  get name() {
    return this._name;
  },
  show: function () {
    console.log(this._name);
  }
};

var des = {
  _name: 'bar'
};

copy(src).to(des);
copy(src).toCover(des);
copy(src).pick('_name', 'name').to(des);
copy(src).pick('_name', 'name').toCover(des);
