The Lodash _.unsplat() method takes a function expecting an array as its last argument and returns a function which works identically, but takes a list of trailing arguments instead of an array.

Syntax:

_.unsplat( function );

Parameters: This method accepts a single parameter as mentioned above and discussed below:

  • function: Original function taking its last arguments as an array.

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

Below examples illustrate the Lodash _.unsplat() method in JavaScript:

Example 1:

Javascript




// Defining lodash contrib variable
var _ = require('lodash-contrib'); 
  
function g (val, arr) {
    return val+" : "+arr;
}
  
var gfgFunc = _.unsplat(g);
  
console.log(gfgFunc("a", 10, 20, 30, 40))


Output:

a : 10, 20, 30, 40

Example 2: 

Javascript




// Defining lodash contrib variable
var _ = require('lodash-contrib'); 
  
function g (arr) {
    return arr;
}
  
var gfgFunc = _.unsplat(g);
  
console.log(gfgFunc(100, 200, 300, 400))


Output:

[ 100, 200, 300, 400 ]

Example 3: 

Javascript




// Defining lodash contrib variable
var _ = require('lodash-contrib'); 
  
function g (val,arr) {
    return arr.join(val);
}
  
var gfgFunc = _.unsplat(g);
  
console.log(gfgFunc(" : ", "GeeksforGeeks", "Computer Science Portal for Geeks"))
