`partial`：允许多参数的函数接受一个数组，指定最左边的部分参数。

```
var multiply2 = (a, b) => a * b;
var double = R.partial(multiply2, [2]);
double(2) // 4

var greet = (salutation, title, firstName, lastName) =>
  salutation + ', ' + title + ' ' + firstName + ' ' + lastName + '!';

* @category Object
* @sig (* -> *) -> {*} -> (* -> *)
* @param {Function} fn The function to bind to context
* @param {Object} thisObj The context to bind `fn` to
* @return {Function} A function that will execute in the context of `thisObj`.
* @see R.partial
* @example
*
*      var log = R.bind(console.log, console);
*      R.pipe(R.assoc('a', 2), R.tap(log), R.assoc('a', 3))({a: 1}); //=> {a: 3}
