Curry example

curry.js

// consider the following function to process bank transaction
const transaction = (fee, balance, amount) => (
  balance + amout - fee;
);

// Simple curry implementation
const curry = (fn, ...args) => (
  (..._arg) => (
    fn(...args, ..._arg)
  )
);

// We could easily reuse the transaction logic for a "free" transaction
const freeTransaction = curry(transaction, 0);

freeTransaction(10, 90); // = 100

1. There is a typo on line 3: amout should be amount
2. On line 14 I believe the second argument should be 0 instead of 10 to make it a free transaction.
