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 👍🏻👍🏻

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

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

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

Great video, well explained and loved to watch it!

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

This was great! Thanks for this Wes!

This is really useful. Thanks a ton Wes!

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

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

Exactly what I was looking for. Thanks!

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.

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

Nice, really nice. Thanks Wes!

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

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

Nested destructuring...wow! SUBSCRIBED

This was very helpful. Thanks a lot.

Very well explained topic.

Never thought this is possible. Crazy.

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

The most helpful video ever.period

This is great. Thank you!

really good explanation 🎉

Thanks Wes!

You go Wes!

Thank u for this awesome video

Extremely helpful!!!

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.

Thank you. I was immediately successful. Thank you!

This is super helpful 🙏

Very helpful, thank you

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

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_

Beautiful ❤️

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

really amazing ;)

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?

Thanks Wes. One question. Are Canadian shoes normal or weird or something else?

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

Wes, How can I map through that nested array?

good video thanks Wes Bos

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

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 ?

dude, thanks

Seems like sacrificing readability at the expense of compactness.

Cool!

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

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.

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

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 👍👌

Good 👍

Asante.

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

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();.

How to get only second element in the array ?

How do I rename the item1 and item2 variables?

how can u make a table with all keys end values

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]

i am having difficulty destructuring this array I want output as R8 below is array var obj = [ { title: "buy meal", isDone: false, }, { title: "come office on time", isDone: false, }, { title: [ "BMW", [ { id: 01, name: "R8" }, { id: 02, name: "r7" }, ], "maruti", ], isDone: true, }, ]; can you help me?

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?

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!

hey, how would destructor the event_general part: const events = { event_id: 57, name: 'Event Name', organiser: 'John', category: 'Music', event_general: [ { venue: 'unknown', country: '2', isVirtual: true, story: 'null' } ] };

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

How to add an object to a nested array of objects dynamically using distinct properties of an object

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.

Neat but pretty hairy!
