@richytong_ Awesome work Richard.
That's a lot if array filter variants, if that's what those are. :)

Quick Tip: Setup Typescript type-checking with your Pure Javascript

@richytong_ I just sent you a "dev dot to" chat message.

But here it is again....

Hey Rich,
Good usecase idea,
timeInLoopAsync

In JS I don't think in terms of null or undefined, but think in terms of "nil".
I use a utility func similar to Ramda's R.isNil

@_ericelliott Here's a python implementation....

@WebDevCaleb It's a big reason I was never a React Redux fan; Switch statement overload. :)

My codebase search found switch statements in some autogen and downpiling code.

And I commonly see it in server code pivoting on the HTTP method type, eg, this autogen Netlify boilerplate code....

An example of #MethodChaining vs #FunctionalPipelines.

Conceptually very similar.
But #FP has a number advantages over MC.
eg:
custom pure functions
point-free software design
and others I'll elaborate soon!

#techtips

write out workflows

add docs to every function, describe the why

consider all ways to solve a problem

think big picture, in systems terms

graph out your app

clone and run open source repos
- perf test & document where top bottlenecks are

sleep on tough problems

@samantha_ming Hey Samantha, here's another slight variation....

If you prefer a functional approach to programming, here's an example of the simplest way to simulate creating instances of a data class.

@recoiljs @recoiljs I was wondering if you could make available the source code for your sample drag 'n drop demo that you use to explain the Recoil state management library in your presentation video
I would love to tinker with it locally.
Thank you!

@_ericelliott I actually iterate more on the #documentation than the software code itself.

If you can't explain it in #NaturalLanguage, you may not fully understand it, or it may be too complex.

How to do #PipeOrientedProgramming in Python.

With an example doing simple arithmetic operations,
as the result of one function is piped into the next.

The "lNum" util function means "log number".

@robbie_carlton @EriPDev @dan_abramov a closure without declared local state...

const outerFunc = v => () => console.log(v);

outerFunc("hello")();
//=> hello

@mountain_ghosts @dan_abramov If you don't clarify, you're going to be disappointed.

Don't assume that interviewers are perfectly fair, knowledgable or experts at interviewing.

Take assertive responsibility for yourself and your success.

Don't depend on others being obligated to make your success easier.

[Functional_JS @Reactivizer]

@mountain_ghosts @dan_abramov Always be sure to ask...

"Are there any constraints?"
or
"Is there a preferred style you'd like the code to be in?"

Also be sure to ask upfront to look at some of the company's code, to see where they are in the architectural, best-practices, and readability scheme of things.

@samantha_ming Nice work Samantha!
Keep the goodies coming!
