JavaScript is a powerful language. We can create games, spreadsheet apps, mail clients, and so on, with JavaScript. However, developing applications using JavaScript ends up messy if you aren't careful.
It's a good thing that we are using a JavaScript framework/library to clean up redundant and messy code.
Lodash is one of the most used JavaScript libraries, and it makes it easier to develop JavaScript code, such as walking through arrays, working on objects and their properties, and so on.
