## validate.js
/*

  For my use only but happy to explain it to anyone interested:

  I'm not into use controlled components everywhere.
  Forms collects the values and submit does... well submit.
  Because of React twisted events (synthetic) this approach uses:
  - every input has a unique name
  - then you will get obj vith name: value keys
  - you can specify which name should be picked up

## perf-concat.js
const makeSmallArrays = count => [ ...(new Array(count)) ].map((_, i) => [i, i.toString()]);

// generate arrs
// a lot of small ones
const countSmall = 1000;
arrOfSmalls = makeSmallArrays(countSmall);

// cost of duplicating array

const fnConcat = arr => arr.concat();
