React.js: setState overwriting, not merging

Question

I\'m quite new to React.JS and I am in the process of experimenting by building a masonry-style layout.

I render each element to the DOM, then I need to loop over eac

Answer 1

Something like:

getInitialState: function() {
    return {
        something: { x: 0, y: 0 },
        blah: 10
    };
}

var state = Object.assign(this.state, {
    something: Object.assign(this.state.something, { y: 50 }),
});

this.setState(state);

Would be better if it was recursive/deep rather than hard coding the tree, but I will leave that up to the reader :)
