@SimonForsberg the star wall. (half serious, half joking)

The star wall has lots of memes, but also lots of testimonials about how easy it is to learn programming languages while reviewing for example.

@Phrancis I've no idea why I did not get pinged for this.

@Phrancis This seems like the approach I would take

Every component should do Exactly One Thing tm. Remember a component is just a function (or a class, if you're using a stateful component).

A component either renders some view (which can include other components) or actually manages the state of a view (and nothing else).

So a UsernameField component would make sense because that component would have to make sense because you have to do validation rules and whatnot, and then you might have a SigninForm component that renders a UsernameField.

You might then also want to reuse the UsernameField in your SignupForm.

This is actually how many form libraries for react already work: You have to create one component per field and wrap the form in a higher order component to enable the 'magic' to work.

All JavaScript uses objects, therefore all JavaScript is OOP :D

Unrelated, there's no advantage in ending statements with semicolons in JS if they are not needed, or is there?

Mat's Mug

2:56 PM

so, Rubberduck works on AMD and crashes on Intel. Aren't race conditions fun?

monking!

Dan Pantry

@Phrancis Nope, none.

There are gotchas though (It IS javascript)

if you don't terminate a line with a semi colon and the next line starts with a paren or square bracket then javascript will interpret that as the two lines being the same thing. That is

foo
(bar)

will mean javascript tries to do foo(bar) rather than foo and then (bar).

but most minifiers and compilers will insert semi colons for you, as long as you avoid those edge cases

Mat's Mug

~~an apple~~ a semicolon ~~a day~~ an instruction keeps ~~the doctor~~ bugs away

2

Phrancis

lol

@Mat'sMug with non-vanilla JS it makes for some semicolons in weird places though... look at the end of this React class for example...

var Toggle = React.createClass({
  getInitialState: function() {
    return { color: green };
  },
  changeColor: function() {
    var newColor = this.state.color === green ? yellow : green;
    this.setState({ color: newColor });
  },
  render: function () {
    return (
      <div style={{background: this.state.color}}>
        <h1>
          <button onClick={this.changeColor}>
          	Change color
          </button>
        </h1>
      </div>
    );
  }
});

Mat's Mug

to that I'd say look at the beginning: var Toggle =

Phrancis

Well, yeah of course ;P

Dan Pantry

3:06 PM

FWIW I believe most of FB's React samples in that manner do actually use semicolons.

If you're using JSX, don't bother. Your compiler will insert them for you.

Which also enables you to drop the surrounding parentheses from the <div style={{....}} in render because those are mainly there just to make it easier to remember where to put the semicolon :D

Phrancis

I thought the inner set of braces was to signify you're injecting an object instead of just a value...

(I've been wrong before ;)

2

Dan Pantry

Sorry, I didn't mean the inner braces in style, i meant the parens surrounding the <div>.

return (
  <div>
  </div>
);

becomes

return <div>

</div>

Phrancis

Can you also do this? :

return
  <div>
  </div>

Dan Pantry

I can. :

That will cause issues with semicolon insertion, so I'm going to say no

If you want to have that on a separate line you need parentheses.

xDaevax

Out of curiosity, how does the omission or inclusion of semi-colons affect readability?

Phrancis

3:10 PM

Not much, IMO^

Dan Pantry

In my opinion the omission removes cruft and makes it easier to read

xDaevax

I know I shudder at work when I see someone omit { } for one-liner conditionals

Dan Pantry

omitting {} can cause many more problems than omitting ;

xDaevax

True.

Dan Pantry

It is ultimately a stylistic choice, Facebook uses semicolons in their samples

The Redux community tends to not use semi colons to make it more Haskelly

Phrancis

3:11 PM

I think the ; inclusion habit is because a lot of languages won't compile without it

Dan Pantry

It's also because ASI can be really tricky to track down.

And that will bite you in the ass if you ever try to minify your code

Which all javascript is (currently, until HTTP/2 comes along)

As long as you remember the rules though and/or use something like TypeScript (where it will tell you if you're doing something silly) you'll be fine

And if you'd rather not have to remember the rules, that's fine, just use semi colons.

Phrancis

Unrelated, can you pretty easily change an element's CSS class(es) with React?

I know with jQuery it's a breeze, and it's something I'd be interested in implementing with React

Dan Pantry

@Phrancis Yep. You use the className prop (not class, because class is a reserved keyword). Then you treat the className like any other state or prop.

Phrancis

Oh, sweet

Dan Pantry

const Toggle = ({ isPressed }) => <button className={isPressed ? 'pressed' : '' } />

Q: Next, greater permutation of digits of a number

Was looking at this question (which I initially misunderstood completely), to which Peter Taylor posted a good answer outlining a much better algorithm. For kicks, I implemented it in Ruby, but I feel like it can be done more cleanly: def next_greater_permutation(integer) digits = integer.to_...

Q: How do you use VBA on excel?

Friend suggested I use a Macro but I'm not really sure how to go about that. https://gyazo.com/60a988cd60a158cebb118925d67d492f you can click on the link as a reference. I have these three cells that are the sum of the cells above them. Basically I want to rank them. When one cell has a highe...

sigh How do people think that a site called "code review" would be a good place to ask a question before code is written..?

Thomas Ward

@xDaevax Because people are people and prone to not understand things

Simon Forsberg

Mat's Mug

Thank you @Mat's Mug! I learned an aweful lot in 15 minutes of reading between your post and my code. You put time and a lot of thought into your response and I appreciate that. There's a lot of good principles to glean from it. — ChrisB Aug 26 at 19:45

Wow. Thank you. I was not expecting to get a good thorough answer THAT quickly. Clearly I should be smoking your stuff. I'll implement whichever changes I can handle and post the updated code with a description of the changes as an answer. — Jeremy Caron Feb 6 at 15:45

Would it be better practice to condense code as much as possible such as: out = var1.substring(0,var.indexOf([char])); System.out.print(out); Or to spread the code out with variables such as: end = var1.indexOf([char]); out = var1.substring(0,end); System.out.print(out);
