Why bind to `this` and not pass as an argument?

[rstacruz]

this is something that is mostly used in cases of prototypal inheritance, which is somewhat counter-intuitive to functional-programming-like approaches.

Instead of a::b() passing a as this to the b() function, why not pass it as the first parameter? that is:

"hello there world"
  :: titlecase()
  :: take(11)
  :: reverse()
  //=> "erehT olleH"

function titlecase (string) { ... }
function take (string, count) { return string.substr(0, count) }
function reverse (string) { return string.reverse() }

This is something that exists in elixir as the pipe operator.

This has been discussed over and over, both here and in ESDiscuss. Please read previous issues before opening new ones. https://github.com/zenparsing/es-function-bind/issues/19

In your case:

function take (count) { return this.substr(0, count) }
function reverse () { return this.split("").reverse().join(""); /* yours was broken*/ }

Etc.
