Computed Property vs Getter

@Caltor wrote:

With the advent of ES6 we can now use getters as in:

export class col {
    constructor(left, width = 140) {
        this.left = left;
        this.width = width;
    }

    get middle() {
        return this.left + this.width/2;
    }
}

Previously I would have used a computed property in the example above to obtain the middle value. Is there any advantage to either approach? The get seems ideal to me as I don’t have to import anything and remember to identify the key fields I will be watching. Just wondered if there are any disadvantages to this (performance?) compared to traditional Ember computed properties or any gotchas of which I need to be aware.
