`setNodeAttributes` should just call `node.data()`

[maxkfranz]

• [ ] Using a selector is slower than cy.getElementById().
• [ ] Use node.data() instead of Object.defineProperty().
• [ ] self.cyj.style().update(); is unncessary.

Thanks, Max. I will make these changes.

Done. package version 0.99.21 @maxkfranz - it took me a while to figure out I needed to make attributeName an array.

node.data({[attributeName]:  newValue});

Yes, that's just es6 syntax sugar for this:

let payload = {};

payload[attributeName] = newValue;

node.data(payload);
