Great article! Easier to use than the actual docs! One thing I avoid using is for...of loops because of inefficiency. Albeit relatively minor compared to network latency, however it is ~80% less efficient compared to the forEach which is also pretty readable.

Thanks @wattry.

I don't worry about micro-benchmarking, since it doesn't matter much (see this video from a V8 developer).

Is it possible to add nested dynamic name property?

x = 'a.prop' const {[x]: b} = {'a': {'prop': 'c'} }

[ahmadjama]

A great article indeed, this explains clearly what it is and how it's done and the examples provided are top notch. Thank you!

Easy to understand article clear and concise. Thank you so much for the help!

[Turbospeedzter]

Thanks. After more study, I understand it. A lot of instructors assume too much when they fly through the code. Yours helped.

I always value your articles and is a regular goto resources for understanding the JavaScript language.

Question - how do I add a property when making a shallow copy of an object?

Thank you Helena @Helena-p!

Question - how do I add a property when making a shallow copy of an object?

One option is to use object spread operator:

const hero = {
  name: 'Batman'
}

const heroCopy = {
  ...hero,
  realName: 'Bruce Wayne' // add the new property here
}

Please check this post for more details.

[Helena-p]

Super! Thank you so much @panzerdp and so quick to answer! :)
