Underscore.js _.flip2() Method

0 0 1 minute read

The _.flip2() method returns a function that works identically to given function but accepts the first two arguments in reverse order. The order of all rest arguments remains the same.

Syntax:

_.flip2( function );

Parameters: This method takes a function that takes some 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:

Javascript

// Defining underscore contrib variable 
var _ = require('underscore-contrib');  
  
function gfgFunc(a, b, c) { 
    return "Value of a is " + 
    a + " and Value of b is " +  
    b + " and Value of c is " + c; 
} 
  
var abc = _.flip2(gfgFunc); 
  
console.log(abc(1, 2, 3));

Output:

Value of a is 2 and Value of b is 1 and Value of c is 3

Example 2:

Javascript

// Defining underscore contrib variable 
var _ = require('underscore-contrib');  
  
function gfgFunc(a, b) { 
    return b + " is " + a; 
} 
  
var gfg = _.flip2(gfgFunc); 
  
console.log(gfg("zambiatek",+ 
   "Computer Science Portal for Geeks"));

Output:

zambiatek is Computer Science Portal for Geeks
