invert-kv

What is invert-kv?

The invert-kv npm package is a simple utility that allows you to invert the keys and values of an object. This means that the keys of the original object become the values of the new object, and the values of the original object become the keys of the new object. It is particularly useful when you need to reverse the mapping of an object for easier access based on values rather than keys.

What are invert-kv's main functionalities?

Inverting key-value pairs

This feature allows you to swap the keys and values of an object. The code sample demonstrates how to use invert-kv to invert the keys and values of a simple object.

{ const invertKv = require('invert-kv'); const original = { a: '1', b: '2' }; const inverted = invertKv(original); console.log(inverted); // Output: { '1': 'a', '2': 'b' } }

Other packages similar to invert-kv

lodash.invert

Lodash's invert function is part of the larger lodash library, which offers a wide range of utility functions for JavaScript. Lodash.invert performs a similar function to invert-kv by creating an object composed of the inverted keys and values of the original object. The main difference is that lodash.invert is part of a larger library, which might not be ideal if you are looking for a package with a singular focus like invert-kv.

reverse-object

Reverse-object is another npm package that provides functionality to reverse the keys and values of an object. It is similar to invert-kv but might have different handling for specific edge cases or performance optimizations. It's another alternative for those looking for a utility focused solely on this task.
