Curry stable method for javascript and Typescript.

Curry.js

// Define new methods, function helper
Function.method = function(name, fx) {
  this.prototype[name] = fx;
};

// Define curry method
Function.method("curry", function() {
  const slice = Array.prototype.slice;
  const args = slice.apply(arguments);
  const that = this;
  return function() {
    return that.apply(null, args.concat(slice.apply(arguments)));
  };
});

// Original function
function add(a, b) {
  return a + b;
}

// creating our curried function, and invoking
const add1 = add.curry(1);
// returns 46
console.log(add1(45));

// invoking our function with no curry
// returns 3
console.log(add(1, 2));
