Lodash _.curryRight2() 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。
_.curryRight2() 方法用于返回给定函数的柯里化版本,其中最多从右到左处理两个参数。
句法:
_.curryRight2( 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:此方法返回一个柯里函数。
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) {
return a / b;
}
// Using the _.curryRight2() method
var curried = _.curryRight2(div);
console.log("Curried division is :",
curried(4)(32));
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function to curry
function div(a, b) {
return a / b;
}
// Using the _.curryRight2() method
var curried = _.curryRight2(div);
console.log("Curried division is :",
curried(32)(4));
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function to curry
function sub(a, b) {
return a - b;
}
// Using the _.curryRight2() method
var curried = _.curryRight2(sub);
console.log("Curried Subtraction is :",
curried(2)(10));
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function to curry
function div(a, b) {
return ("a=" + a + " and b=" + b);
}
// Using the _.curryRight2() method
var curried = _.curryRight2(div);
console.log(curried("a")("b"));
输出:
Curried division is : 8
示例 2:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function to curry
function div(a, b) {
return a / b;
}
// Using the _.curryRight2() method
var curried = _.curryRight2(div);
console.log("Curried division is :",
curried(32)(4));
输出:
Curried division is : 0.125
示例 3:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function to curry
function sub(a, b) {
return a - b;
}
// Using the _.curryRight2() method
var curried = _.curryRight2(sub);
console.log("Curried Subtraction is :",
curried(2)(10));
输出:
Curried Subtraction is : 8
示例 4:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function to curry
function div(a, b) {
return ("a=" + a + " and b=" + b);
}
// Using the _.curryRight2() method
var curried = _.curryRight2(div);
console.log(curried("a")("b"));
输出:
a=b and b=a
