Javascript Destructuring assignment

Key Takeaways

what's up y'all mrs. Hussein also from IG on to where we're just a software engineering by example in this video we will learn about a new concept in JavaScript ESX and it's called destruction assignments alright so let's just get into it guys and show you how this works and Before we jump into this and show you how this new feature works let's let's show you for example guys just how we use to do things guys right like this is this is this is a classic object let's get let's say I have a an object that is called movie and I literally just put a bunch of properties say movie at the title year and rating okay so I just declared the movies right that's that's it so movie Doge here will give you that full video title will give you that right let's just clear very simple stuff so if you won't declare like a variable called Y and you say movie dot here you can do that right you can save the year property or the year object or the U key in a variable that is called Y okay and you can do the same thing right if you print Y says like yeah if you do that like for example you want the rating movie dog waiting and so on right so you can just save all this parameters and this way so that T equal movie dog title okay so this is what how we basically used to do things it's very simple stuff right but what what the destruction assignment allow you to do is kind of unpack that object very nicely using this new format so this is how you're doing this initial you do lead but you understood you declare a variable with a curly braces button you give it a name and that name is very critical that has to exist in one of those properties that you can't just give it any name right this name has to literally exist as wonderful a property which is we know that there is a movie dot here so you can literally do let curly braces here and what will happen here the year will be night people like so this is kind of useless if you think about like a okay I mean yeah alright saves me like what one line of code it's the same thing right but the coolest thing about it is that you can do this guy you can do title coma right only year let's do so what does the other think I'm ready right you can do this and you can unpack as many properties as you want and just like that with one line of code I have the title in a variable and another title another variable so that is a pretty cool ish is in a guys isn't it I think it's pretty cool alright so another property of the destruction assignment I don't know why they called destruction I saw an ant right so I think it's just like you can unpack stuff and put it like into its distinct variables if you will right so so let's let's try to do another kind of destruction many times this video will be very short guys so another way of just unpacking subtle using arrays right you can do stuff with array so you can you can do something like that guys so you can do a be equal and our way that is called I don't know number seven and nine you can do that right so a now is equal seven and be Zack or nine right and here's the coolest part about this guy's you can do a B is equal BA well well what this will do guys what do you think this will do I mean people who are done does Python probably will know what this does right we we JavaScript boys are kind of late in the game for this but this actually doesn't swap if you think about it so now a is a nine and B is a seven right so again you can do all kind of schoolish stuff guys with this so this is what I want to talk about to do it guys so very simple stuff right just like new ways that simplifies your life so guys hope you enjoy this video but I see on the next video with some more cooler steps see you there guys goodbye
