How does lodash.method work?

lodash.method is a function in the Lodash library for JavaScript that creates a new function that returns a value for a specified method of an object.

When lodash.method is called with an object and a method name as input, it performs the following operations:

It creates a new function that accepts arguments for the specified method.
When the new function is called, it calls the specified method on the input object with the provided arguments.
It returns the return value of the specified method, or undefined if the method does not exist.

By using lodash.method, developers can create functions that can be used to retrieve values from objects in a more concise and flexible manner. This function can be used in a wide variety of situations, from creating simple getter functions for object properties to wrapping complex methods with custom argument handling. Note that lodash.method may not work as expected with certain types of objects or methods, so it is important to test thoroughly before using it in production code.

const _ = require("lodash");

// Creating a function to retrieve the length of a string
const stringLength = _.method("length");

// Using the function to retrieve the length of a string
const length = stringLength("hello");

console.log(length); // Outputs: 5

In this example, we're using lodash.method to create a new function, stringLength, that returns the length property of its input. We then use this function to retrieve the length of the string "hello", which is 5. Note that in this example, we're passing the string "length" directly to _.method, which creates a function that retrieves the length property of its input without requiring any additional code.
