The _.splat() method takes a function that accepts one or more arguments and hence returns a function that takes an array and uses its elements as the arguments to the original function.
Syntax:
_.splat( function );
Parameters:
- function: original function containing arguments.
Return Value: This method returns a function.
Note: This will not work in normal JavaScript because it requires the underscore.js contrib library to be installed.
underscore.js contrib library can be installed using npm install underscore-contrib –save.
Example 1: In this example, we will see the use of the _.splat() method.
javascript
// Defining underscore contrib variable const _ = require( 'underscore-contrib' ); function addNum(a, b) { return a + b; } let listTwoNamesFromArray = _.splat(addNum); console.log(listTwoNamesFromArray([1, 2])); |
Output:
3
Example 2: In this example, we will see the use of the _.splat() method.
javascript
// Defining underscore contrib variable const _ = require( 'underscore-contrib' ); function addNum(a, b) { return a + " : " + b; } let listTwoNamesFromArray = _.splat(addNum); console.log(listTwoNamesFromArray( [ "neveropen" , "Computer Science Portal for Geeks" ])); |
Output:
neveropen : Computer Science Portal for Geeks
