An example of a currying in JavaScript

currier.js

var currier = function(fn) {
  var args = Array.prototype.slice.call(arguments, 1);

  return function() {
    return fn.apply(this, args.concat(
      Array.prototype.slice.call(arguments, 0)));
  };
};

sequence.js

var sequence = function(start, end) {
  var result = [];

  for (var i = start; i <= end; ++i) {
    result.push(i);
  }

  return result;
};

var seq5 = currier(sequence, 1);
seq5(5)
