Lodash _.unsplat() Method
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
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
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
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" ))
|
Output:
GeeksforGeeks : Computer Science Portal for Geeks
