How does commander.mangleProps work?

Commander.mangleProps works by iterating over the keys of an object and replacing any hyphen-separated keys with camelCase keys. The function takes an object as input and returns a new object with the modified keys. It uses a regular expression to match hyphen-separated keys, and then uses the replace() method to replace the hyphens with empty strings and capitalize the first letter of each subsequent word. This creates a new object with keys that are formatted in camel case, which can be more convenient to work with in some situations. Commander.mangleProps can be useful in situations where it is necessary to convert objects with hyphen-separated keys to objects with camelCase keys, such as when working with command-line arguments or configuration files. By standardizing the naming convention, this can help to simplify code and make it more consistent and easier to read.

const { mangleProps } = require("commander");

// Define an object with hyphen-separated keys
const originalObject = {
  "first-name": "John",
  "last-name": "Doe",
  "phone-number": "555-1234",
  "email-address": "john.doe@example.com",
};

// Convert the object to camelCase format
const camelCaseObject = mangleProps(originalObject);

// Output the result to the console
console.log(`Original object: ${JSON.stringify(originalObject)}`);
console.log(`Camel case object: ${JSON.stringify(camelCaseObject)}`);

In this example, we use Commander.mangleProps() to convert an object (originalObject) with hyphen-separated keys to an object with camelCase keys. The function replaces the hyphen characters with empty strings and capitalizes the first letter of each subsequent word, creating a new object that is formatted in camel case. We output both the original object and the camel case object to the console. In this case, the original object has hyphen-separated keys, and the camel case object has keys formatted in camel case.
