Lodash _.curry() method returns a curried version of the given function. it accepts an arity which is a number that shows it will keep accepting arguments until it has received this number of arguments or invocings.
Syntax:
_.curry(fun, [arity=fun.length])Parameters:
- fun: This is the given function.
[arity=fun.length]: The arity of the function
Return Value:
- It returns a curried version of the function.
Example 1: In this example, we are passing numbers to the gfgFunc which stores the result of the lodash _.curry method and prints the result in the console.
// Defining lodash contrib variable
let _ = require('lodash');
// Function
function fun(a, b, c, d) {
return a + b + c + d;
}
// Making curried function
let gfgFunc = _.curry(fun);
// Only operates for arguments same
// as the number in function
console.log("Addition is :",
gfgFunc(42)(23)(20)(30));
// Not adds for less arguments
console.log(gfgFunc(1)(2)(3));
Output:
Addition is : 115

Example 2: In this example, we are passing numbers to the gfgFunc which stores the result of the lodash _.curry method and prints the result in the console.
// Defining lodash contrib variable
let _ = require('lodash');
// Function
function fun(a, b, c) {
return a * b * c;
}
// Making curried function
let gfgFunc = _.curry(fun);
// Only operates for arguments same
// as the number in function
console.log("Multiplication is :",
gfgFunc(20)(23)(27));
// Not multiplies for less arguments
console.log(gfgFunc(1)(2));
Output:
Multiplication is : 12420
