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.

} 
  
// Using the _.partial() method
