Wow! The most productive minutes I've spent all month. Thanks! 😀

Can't believe now I get how nested object destructuring works! Reading the doc on MDN confuse the heck out of me because they didn't mention that the parent variable becomes undefined when destructuring its child object property. Good stuff 👍🏻👍🏻

You're a legend Wes, thanks for all your effort 👍

I needed this... Honestly I still need it, but I wish I had found these videos before writing an insane loop.

Thanks Wes! Even when I think I know the topic I end up learning something

Thank you! I was so confused until I found this.

You are amazing! i come back here at least once a week

Great video, well explained and loved to watch it!

Exactly what I was looking for. Thanks!

This was great! Thanks for this Wes!

This is really useful. Thanks a ton Wes!

I certainly learnt a thing or two :) You are an amazing teacher. Thanks you

Just Superb :). I love the way you explained with super energy :)

I was also facing this nested problems ... but from tomorrow no complain no demand Thankyou very much sir..🙌

The most helpful video ever.period

Wow , Really Really amazing point that you mention , I love the way and I want to use it in my daily projects

this was very handy for me, thanks so much

This is also great when you combine it with Spread, Rest. Makes everything a lot cleaner

This is super helpfull Wes!! 😎👍 thanks for sharing!

I think it would've been great had you pointed out that one can of course write destructuring constructs across multiple lines. Because if you destructure nested objects and you write the destructuring the same way that you would write the object if you were to create it, it becomes very clear and easy to read.

Nice, really nice. Thanks Wes!

Wow. That was fantastic. Thank you

Nested destructuring...wow! SUBSCRIBED

Great video, love it. Thank you sir!

great video. Love your enthusiasm :)

cool tutorial so straightforward

This was very helpful. Thanks a lot.

That was a great video. very useful. thanks bro.

Very well explained topic.

Extremely helpful!!!

Never thought this is possible. Crazy.

really good explanation 🎉

This is great. Thank you!

Thank you. I was immediately successful. Thank you!

Thank u for this awesome video

You go Wes!

Uaaau here I was all confused about this black magic fuckery just to find out it's actually rather simple and useful after watching this video. Kudos to Wes! You're the man.

Love the display. Especially how the attributes are in italics. Which them are you using?

Thanks Wes!

Been using this technique for years... I finally know what the definition is haha

Very helpful, thank you

Seems like sacrificing readability at the expense of compactness.

@@devincustodio2258 as someone with 20 years professional experience as a software engineer and now the director of the department at the agency I’m with, I’ve met many engineers with CS degrees who were half the programmer of some self taught developers. A degree doesn’t necessarily automatically mean someone is qualified in a real world position.

I'm testing this out on console in the same window as I'm watching the video. I love how simple and neat this is. - I was wondering how I could back up a level to get a parent of something already destructed. Kind of dummie, but if any else is wondering: *var data = { foo: { bar: 1 } };* Say we want to get to *bar* but still want *foo* to be available: *const { foo, foo: { bar } } = data;* *> foo* _{bar: 1}_ *> bar* _1_

really amazing ;)

Beautiful ❤️

Thanks Wes. I've been trying to send nested form input values using the window.fetch API, do I destructure the inputs or just send the form values as is?

Would be nice if that nested destructuring worked on imports specifically when importing json since Webpack can now tree shake those

Your font in editor is great, what is name of that font and color scheme? as I searched many but nothing resembling this font typeface.

I just found it on Wes's blog; it's Operator Mono, but it's $200.

I did not understand quite well how it helps in the example of react when you have to pass like 10 items as props.You will still have 10 lines of code.Any explanation ?

can you suggest some good plugin for formatting the JSX code in VSCode ? I have components within components and each component have their own props, its such a waste of time manually pressing tab to fix the formatting to improve readability

And we can also provide a default value for keys that are missing.

Wes, How can I map through that nested array?

Thanks for the useful one. what if object is nested very deeply ? i mean more than 10 items deeper ??

Siiiiiiick video, sick sick sick. 💪🏻

dude, thanks

good video thanks Wes Bos

Great Video. Have been looking for this. Can someone help me with this question. How can i just pull only name from the items in the array. I don't need the other data just all the names inside the array.

Although this is kind of cool, there are two things to consider: readabily is quite poor (which is my subjective opinion) but VERY IMPORTANT: THERE IS NO HANDLING OF UNDEFINED / FALLBACK VALUES. If you destructure only one level deep, you will get no errors if something is undefined, instead you can test it in ongoing code. When trying to destructure from undefined, you will get an error. So when working with uncertain data, like from an api, i would highly recommend NOT to do use deep nested destructuring!

You can even omit properties/keys with rest spread and destructering. const { status, ...rest } = makeItem() Rest now only contains data.

@Nemcoification

Just in case anyone's wondering, the same is true for arrays like: const [ status, ...rest ] = makeItem(); Arrays have the added benefit of just being able to skip the variable entirely by just doing const [ , ...rest ] = makeItem();.

Can you show how to render these nested objects into a table? I am easily able to console.log those items but I am struggling with the display of the tables. I can't use the map() function.

Super 👍👌

Asante.

how can u make a table with all keys end values

What if i need 2nd element of array (item2)

Is there a way to only destructure the second item in an array, without destructuring the first?

yes, arrays are just objects in js. so you could do const {1:s2}= [1,2,3]

You may have to play this video at half the speed.

Hi Wes, thanks a ton for this breakdown. I've still got a little confusion on how you make multiple variables from the same function and/or data set? For example, let's say I wanted to make *4 different variables* from the *makeItem()* function... how could I do that w/ out having to make *4 different makeItem()* functions? I put together a codepen here: codepen.io/oneezy/pen/VXWLXa?editors=0011

@moosecouture1

I do not see where your codepen is showing any changes... but if I understand your question... if it is like what is being shown here with destructuring... you could pass it an array and destructure the array `const [ one, two, three, four ] = [makeItem(), makeItem(), makeItem(), makeItem()]` Otherwise I do not know how it falls into the scope of this quick tutorial.

@ethanstewart8957

Not sure I fully understand the question. Are you talking about having data, item, etc. also be variables when you're four levels deep?

If the parent is an array with a nested object or visa versa and their children are arrays nested in objects or visa versa, it can all be so overwhelming and confusing.

ur so cool

Neat but pretty hairy!
