Lodash _.curry2() 方法
Lodash _.curry2()方法返回给定函数的柯里化版本,但将恰好柯里化两个参数,不多也不少。
句法:
_.curry2( fun )
参数:此方法采用上面列出并在下面讨论的单个参数。
- fun:这是给定的函数。
返回值:它返回函数的柯里化版本。
注意:要执行以下示例,您必须使用此命令提示符安装lodash-contrib库并执行以下命令。
npm install lodash-contrib
示例 1:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function
function fun(a, b){
return a * b;
}
// Making curried function
var gfgFunc = _.curry2(fun);
// Only operates for exactly two arguments
console.log("Multiplication is :",
gfgFunc(2)(23));
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function
function fun(a, b){
return a + b;
}
// Making curried function
var gfgFunc = _.curry2(fun);
// Only operates for exactly two arguments
console.log("Addition is :", gfgFunc(25)(23));
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function
function fun(x, y){
return arguments;
}
// Making curried function
var gfgFunc = _.curry2(fun);
// Shows only two arguments
console.log("Curried Arguments are :",
gfgFunc("arg1")("arg2"));
输出:
Multiplication is : 46
示例 2:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function
function fun(a, b){
return a + b;
}
// Making curried function
var gfgFunc = _.curry2(fun);
// Only operates for exactly two arguments
console.log("Addition is :", gfgFunc(25)(23));
输出:
Addition is : 48
示例 3:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function
function fun(x, y){
return arguments;
}
// Making curried function
var gfgFunc = _.curry2(fun);
// Shows only two arguments
console.log("Curried Arguments are :",
gfgFunc("arg1")("arg2"));
输出:
Curried Arguments are : [Arguments]
{ '0': 'arg1', '1': 'arg2' }
