How to validate an object using a Proxy class #shorts

Showing a cool trick to use the proxy class to validate an object's properties when they change.

------------

Actually, that's really cool. Being able to create your own validator.

You don’t even need a proxy or a class. You can just define setters on object either via a "{ set field(value) { … } }" syntax, or via

I find proxies useful when intending to override operators (like providing value equality for objects) or when trying to trace properties we don’t know about in advance.

Getting your channel was the hidden JS Gem
Like how did I not know about this 😅😂
Thanks a lot

damn. this is kind of what I miss from programming languages like Java. this is a great solution, thank you!

I would just use a class for Person as you can apply this very logic inside the definition

[gyanshodhak]

this is a lifesaver, but now TS can handle this with much easier syntax

Proxies are cool, I’ve seen a useRef, context and proxies implement of global state

Looks like a longwinded way of doing simple OOPS accessor mutator logic. Js has done it again, reinventing the wheel

This guy is awesome no other Youtuber taught me all the hidden features of Js can you do more of React.

Did not know about this. Great! I have used the checkvalidity on inputs and that works great too. Also takes regex thru its params

Just use a class with private properties, and add a setter which contains the validation

[mcperera]

Wooh ❤ I can’t believe how little i know about JavaScript

[zimcoder]

Good to know, I wish it was handled as cleanly and as simple as in C# or Java.

That's a whole lot of code for just a setter function

Today I learned something new and useful

[MrBrandenS]

Seems to very much function like decorators, thanks for sharing

[ll_dutch]

I like it, videos like these are nice

[perfect.stealth]

I did not know this. That's awesome asf 👏

[bogdanstanciu]

that's really cool, I wasn't aware of this.
