Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.
The _.overArgs() method is used to create a function that invokes func with its arguments transformed using the given transforms function.
Syntax:
_.overArgs(func, transforms )
Parameters: This method accepts two parameters as mentioned above and described below:
- func: This parameter holds the function to wrap.
- transforms: This parameter holds the function that specifies the argument transforms. It is an optional parameter.
Return Value: This method returns the new function.
Example 1:
Javascript
// Requiring the lodash library const _ = require("lodash"); // Function to calculate the// Cube of a numberfunction Cube(number) { return number * number * number;}// Function to calculate the// triple value of a number function Triple(number) { return number * 3;} // Using the _.overArgs() method var func = _.overArgs(function(a, b) { return [a, b];}, [Cube, Triple]);// print the output console.log(func(3, 5)); |
Output:
[27, 15]
Example 2:
Javascript
// Function to calculate the// double value of a numberfunction doubled(number) { return number * 2;}// Function to calculate the// square value of a number function square(number) { return number * number;} // Using the _.overArgs() method var func = _.overArgs(function(a, b) { return [a, b];}, [square, doubled]);// print the output console.log(func(5, 8)); |
Output:
[25, 16]
