Lodash _.curry2()方法r返回給定的咖喱版本函數但是會確切地說出兩個論點,或多或少。
用法:
_.curry2( fun )
參數:此方法采用上麵列出和下麵討論的單個參數。
- fun:這是給定的函數。
返回值:它返回該函數的當前版本。
注意:要執行以下示例,必須使用此命令提示符安裝lodash-contrib庫,並執行以下命令。
npm install lodash-contrib
範例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));
輸出:
Multiplication is:46
範例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));
輸出:
Addition is:48
範例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"));
輸出:
Curried Arguments are:[Arguments] { '0':'arg1', '1':'arg2' }
