Lodash _.curry3() 方法
Lodash _.curry3()方法返回给定函数的柯里化版本,但会柯里化三个参数,不多也不少。
句法:
_.curry3( 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, c){
return a - b - c;
}
// Making curried function
var gfgFunc = _.curry3(fun);
// Only operates for exactly
// two arguments
console.log("Subtraction is :",
gfgFunc(24)(22)(1));
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function
function fun(a, b, c){
return a + b + c;
}
// Making curried function
var gfgFunc = _.curry3(fun);
// Only operates for exactly
// two arguments
console.log("Addition is :",
gfgFunc(25)(23)(1));
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function
function fun(x, y, z){
return arguments;
}
// Making curried function
var gfgFunc = _.curry3(fun);
// Only operates for exactly
// three arguments
console.log("Curried Arguments are :",
gfgFunc("arg1")("arg2")("arg3"));
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function
function fun(x, y, z){
return arguments;
}
// Making curried function
var gfgFunc = _.curry3(fun);
// Only operates for exactly three
// arguments
// For two args, this method returns
// function info
console.log("Curried Arguments are :",
gfgFunc("arg1")("arg2"));
输出:
Subtraction is : 1
示例 2:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function
function fun(a, b, c){
return a + b + c;
}
// Making curried function
var gfgFunc = _.curry3(fun);
// Only operates for exactly
// two arguments
console.log("Addition is :",
gfgFunc(25)(23)(1));
输出:
Addition is : 49
示例 3:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function
function fun(x, y, z){
return arguments;
}
// Making curried function
var gfgFunc = _.curry3(fun);
// Only operates for exactly
// three arguments
console.log("Curried Arguments are :",
gfgFunc("arg1")("arg2")("arg3"));
输出:
Curried Arguments are : [Arguments]
{ '0': 'arg1', '1': 'arg2', '2': 'arg3' }
示例 4:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Function
function fun(x, y, z){
return arguments;
}
// Making curried function
var gfgFunc = _.curry3(fun);
// Only operates for exactly three
// arguments
// For two args, this method returns
// function info
console.log("Curried Arguments are :",
gfgFunc("arg1")("arg2"));
输出:
[Function: mustBeUnary]
