Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.

The _.partial() method is used to create a function which invokes the given func function with prepended partials to the arguments it receives.

Syntax:

_.partial( func, partials )

Parameters: This method accepts two parameters as mentioned above and described below:

func: This parameter holds the function to partially apply the arguments to.
partials: This parameter holds the arguments to be applied. It is an optional parameter.

Return Value: This method returns the new partially applied function.

Example 1:

Javascript

// Requiring the lodash library   
const _ = require("lodash");   
  
// Given Function 
function info(information, name) { 
  console.log(information + ' ' + name); 
} 
  
// Using the _.partial() method   
var call_gfg = 
  _.partial(info, 'zambiatek'); 
call_gfg('is a computer science portal for zambiatek');

Output:

'zambiatek is a computer science portal for zambiatek'

Example 2:
