The Lodash _.curry3() method returns a curried version of the given function but will curry exactly three arguments, no more or less.

Syntax:

_.curry3( fun )

Parameters: This method takes a single parameter as listed above and discussed below.

• fun: This is the given function.

Return Value: It returns a curried version of the function.

Note: To execute the below examples, you have to install the lodash-contrib library by using this command prompt and execute the following command.

npm install lodash-contrib

Example 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));

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"));

Output: 

[Function: mustBeUnary]
