A little fun with Javascript

Just playing around with the spread operator and I found a neat little design pattern I think I am going to work in:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

let testArr = [9,1, 2, 6, 3, 4];
const newMax = (arr) => {
  if(arr.length === 1) { return console.log('end')};
  var [a, ...arr] = arr;
  let max = Math.max(a,...arr);
  console.log(max ,' >=', ...arr);
  newMax(arr);
}
newMax(testArr);
//output
9 ' >=' 1 2 6 3 4
6 ' >=' 2 6 3 4
6 ' >=' 6 3 4
6 ' >=' 3 4
4 ' >=' 4
end

Seems a fun way to look for edges like in the water trap toy problem? I am not sure, but it will be fun to play around with it.

Another thing that used to annoy me was how you had to use string concatenation. It just looked so ugly. I finally (okay I am late to the party) started using backticks for multi-line parties!

var motion = `Le mouvement de lacet sur la berge des chutes du fleuve,
Le gouffre à l’étambot,
La célérité de la rampe,
L’énorme passade du courant
Mènent par les lumières inouïes
Et la nouveauté chimique
Le voyageurs entourés des trombes du val
Et du strom.`

And finally a little more fun with the spread operator (thanks Alex Rauschmayer) but you can make an array only contain unique values in a very clean, native way.

const arr = [7, 3, 1, 3, 3, 7];
[...new Set(arr)]
//returns
[ 7, 3, 1 ]

Front Ends… who needs em!

I have always preferred to work on the back end. It seems more peaceful there. The front end is all colors, moving stuff, and clicks!! Why should I care about clicks… I respond to requests no clickity click click demands! I am fine seeing JSON shoved on the screen, I will parse it visually, personally. I don’t need fancy filters, sorters and interfaces for data.

This opinion puts me most certainly in the minority, so as every good developer does, I forced myself to do something that made me uncomfortable, make a front end. A little background, the project is a way for me to organize my interviews. I needed a place to hold the questions, let me run through them, add notes, and rate the candidate etc.

The api was written with hapijs, my new personal favorite node framework. I was waffling about what to choose for the client side of things. I have already built a few things with Angular 1.5 so I was contemplating Angular 2, but that would go against the reason I am doing this in the first place. I mean if I am going to go out of my comfort zone, it might as well be way out. I could do it in pure vanilla js, but again I am quite familiar with that.. Come on John! Think… think… A-ha! React. I hear about it constantly. It seems to solve some issues with rendering speeds. It has cool terms like ShadowDOM and JSX that remind me of hackers and superbikes in a cyberpunk movie.

“ShadowDOM leapt, turning mid-air. Using a neural link to control JSX superbike, it started just before her ass slammed into the seat and exploded violently forward…”

I am a few days in now. I have the basic CRUD working, and you know what? I don’t hate it! I like the way react apps come together. Nice and modular, with plenty of opportunity to build reusable components, really fun stuff. So I guess the lesson learned is to keep yourself confused and uncomfortable. Sounds like fun!
