A better order for the arguments to the map function

map-functional-args.js

// One suggestion I have on the way I wrote map in this video:
// https://www.youtube.com/watch?v=qTeeVd8hOFY
// Instead of passing the transform function as the last param
// and the array as the first... it would be better to pass the
// transformFn first and the array as the last parameter to map.

function map (transformFn, array) {
  const rv = []
  
  for (let i = 0; i < array.length; i++) {
    const nextItem = array[i]
    const mappedItem = transformFn(nextItem)
    rv.push(mappedItem)
  }
  
  return rv
}

// The reason this would be better is because if the mapped function
// was curried (see my other video), then we could write a function
// such as...
const _map = curry(map)
const addTenToAll = _map((n) => n + 10)
addTenToAll([1, 10, 11, 20])  // [11, 20, 21, 30]
