JavaScript Proxies

JavaScript has Proxy Objects that were introduced between 2012 and 2016 depending on the browser. They are like enhanced getter and setter traps that you can define and control for any object.
They can be useful for protecting and sealing object properties, for handling missing or misnamed properties and for doing validation on data.

Nice, when I see this stuff I always try to imagine what kind of application would need this feature

[@tahasoft1]

Great video. What is the benefit to using Reflect? Just the static methods that are defined on it? I notice its not a constructor so It looks like it only gives access to certain static methods. Is this all it does? And is it mainly used in accordance with Proxies? Ive never seen it used anywhere else. Thank you for this content. Learn something new about JS everyday.

[@SteveGriffith-Prof3ssorSt3v3]

Yeah. Generally used with Proxies as an easy way to access the object that is being passed to the proxy.

Looks like I have some refactoring to do. 😀

Hi,
can you share your vscode settings/theme?
I want those equality three horizontal lines instead of the ugly look of '==='.
Thanks :)

Please give me the name of the plugin that makes such beautiful array functions)

[@SteveGriffith-Prof3ssorSt3v3]

No plugins being used to create the Array.map function, just code complete with VS Code. I do have the Prettier extension that does some minor formatting of my code.

[@MrLinuxFreak]

so its basicly an object middleware?

[@SteveGriffith-Prof3ssorSt3v3]

That's a good way to look at it.
