I would rather understand the basics really well than memorize all kinds of complicated concepts I can’t stitch together and can’t rederive from the basics. If you can’t rederive concepts from the basics as you need them, you’re lost. You’re just memorizing. ((NAVAL RAVIKANT))

Question is a dangerous word.
It poses the threat to silent tyranny.

 People have become accustomed to the state of abstraction
 and they think it's the correct approach
  and they happily contribute to the mess
  by adding even more abstraction.
 

qsort []     = []
qsort (x:xs) = 
  qsort smaller ++ [x] ++ qsort bigger
    where
     smaller   = [y | y <- xs, y < x]
     bigger    = [y | y <- xs, y >= x]
     
  

qsort [] = []
qsort (x:xs)  =  qsort [y | y <- xs, y < x] ++ [x] ++ qsort [y | y <- xs, y >= x]
    

  let rnd = Math.random().toString(2).slice(2)
  return [...Array(10)].map((_,i)=>+rnd[i])

  let rnd = Math.random()*10**10
  return [...Array(10)].map((x,i)=>(rnd>>i)&1)

function quads(a,b,c){
  let z = Math.sqrt((b*b)/(4*a))
  let w = Math.sqrt(c+z*z)
  let y = Math.sqrt(a)
  let x0 = (w-z)/y
  let x1 = (w+z)/-y
  return [x0,x1]
}
