Lodash _.curryRight() 方法

Lodash 是一个基于 underscore.js 的 JavaScript 库。 Lodash 有助于处理数组、字符串、对象、数字等。

_.curryRight() 方法用于返回给定函数的柯里化版本,其中给定参数从右到左处理。

句法:

_.curryRight( fun )

参数:此方法采用上面列出并在下面讨论的单个参数。

  • fun:这是柯里化版本中应该使用的函数。

返回值:该方法返回柯里函数。

注意:此方法在普通 JavaScript 中不起作用,因为它需要安装 Lodash contrib 库。可以使用npm install lodash-contrib –save 安装 lodash- contrib 库

示例 1:

Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib'); 
  
// Function to curry
function div(a, b, c) {
    return a / b / c;
}
  
// Using the _.curryRight() method
var curried = _.curryRight(div);
  
console.log("Curried division is :",
    curried(3)(3)(99));


Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib'); 
  
// Function to curry
function div(a, b, c, d) {
    return a - b - c - d;
}
  
// Using the _.curryRight() method
var curried = _.curryRight(div);
  
console.log("Curried Subtraction is :",
    curried(2)(1)(6)(44));


Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib'); 
  
// Function to curry
function div(a, b, c) {
    return ("a=" + a + " and b=" + b +
            " and c=" + c);
}
  
// Using the _.curryRight() method
var curried = _.curryRight(div);
  
console.log(curried("a")("b")("c"));


输出:

Curried division is : 11

示例 2:

Javascript

// Defining lodash contrib variable
var _ = require('lodash-contrib'); 
  
// Function to curry
function div(a, b, c, d) {
    return a - b - c - d;
}
  
// Using the _.curryRight() method
var curried = _.curryRight(div);
  
console.log("Curried Subtraction is :",
    curried(2)(1)(6)(44));

输出:

Curried Subtraction is : 35

示例 3:

Javascript

// Defining lodash contrib variable
var _ = require('lodash-contrib'); 
  
// Function to curry
function div(a, b, c) {
    return ("a=" + a + " and b=" + b +
            " and c=" + c);
}
  
// Using the _.curryRight() method
var curried = _.curryRight(div);
  
console.log(curried("a")("b")("c"));

输出:

a=c and b=b and c=a
