Output:
Subtraction is : 1
Example 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)); |
Output:
Addition is : 49
Example 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")); |
Output:
Curried Arguments are : [Arguments]
{ '0': 'arg1', '1': 'arg2', '2': 'arg3' }
Example 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")); |
