In our case, scripting means that the language gives a computer program, an interpreter, written instructions that it executes directly, one script at a time. This stands in comparison to compiled languages such as C++ or Golang where your source code must be translated into bytecode by a compiler before it can be run by an interpreter and turned into machine code.
What is Document Object Model?
Document Object Model (DOM) is a cross-platform programming interface that represents an HTML document on the Web in the form of a tree with nodes and objects. This enables a program to interact with the page, changing or managing its structure, style, and content.

|Language type||A scripting language that uses an object-oriented programming (OOP) approach but does not require compilation to be executed.||A pure object-oriented programming (OOP) language where the code first needs to be compiled before it can be executed.|
|Object model||Prototype-based OOP inheritance. This means that a prototype is itself an object instance, and inheritance is implemented via the process of cloning existing objects.||Class-based OOP inheritance. This means that inheritance is built around the parent-child relationship between classes, and a class defines a type which can be instantiated at runtime.|
|Type checking||Dynamically-typed. This means that code refactors tend to be more localized and you spend less time debugging syntax and semantic errors.||Statically-typed. This means reduced likelihood of some kinds of errors (e.g. logical errors that could occur if you’re not careful in a dynamically typed language).|
|Concurrency||Event-driven approach. This means that an application processes one task at a time using callbacks, an event loop, and a queue.||Thread-based approach. This means that an application divides work up among CPU threads, leaving the quality of performance to hardware capacity.|
Before we get to the most common choices, along with their features, benefits, and use cases, let’s first understand what is the difference between a JS library and JS framework.
Generally speaking, a JS library is a reusable piece of code that is usually focused on one specific use case. Depending on the purpose, a library can consist of different functions, objects, and methods that your developers can reuse and even repurpose. If utilized correctly, a library can save your development team significant time and effort on certain tasks like, for example, implementing form validation on your website, instead of coding it from scratch.
On the other hand, there’s a JS framework, a software platform that can utilize multiple libraries and serves as the groundwork for your future software solution. A framework provides you with hooks and callbacks that your developers can build upon. Equipped with predefined classes, workflows, and functions, a framework helps direct your team on the architecture for your project. It serves as sort of a blueprint that your team can populate with input data to meet your unique requirements, saving you money and time on development.
The main difference between a JS library and a JS framework lies in the flow of controls. A JS library contains snippets of ready-made code (particular app functions that your developers arrange into a workflow), while a JS framework is in charge of running these workflows (calling the code and using it in a specific way). This being said, a library in a way gives your developers greater freedom over the code structure than a framework.
D3.js (a.k.a. Data-Driven Documents) is another popular JS library that developers use for its powerful data visualization features. Much like jQuery, this great tool uses CSS selectors to perform data-driven transformations. D3.js supports a wide range of dynamic behavior features, including datasets for animations and interactions. This enables developers to do all kinds of transitions and manipulations to create anything from simple bar charts to complex data visualizations such as an interactive 3D surface plot. D3.js also features a vast collection of more than 50 different modules, each with its own purpose. The library provides your team with means to build graphical complexity within satisfying performance rates.
Underscore.js and Lodash
A fork of Underscore.js, Lodash was released three years later as a drop-in alternative with better performance, customization, and a more consistent cross-environment iteration support for functions. Back in 2012 many of the Underscore.js contributors moved over to the Lodash camp as the fork offered more features and better documentation.
AngularJS and Angular (2+)
On December 31, 2021, however, Google will cease the support of AngularJS in favor of Angular, also known as Angular 2+, the TypeScript-based rewrite of AngularJS that features a simpler expression syntax, modularity, dynamic loading, and a robust command-line interface. And even though AngularJS will most certainly stay relevant for a while, the lack of updates and the obvious advantages of its competitor make Angular 2+ an indisputable, better choice for a fresh, long-term project.
Node.js and Express
Node.js is widely used in the development of fast and scalable network solutions such as real-time communication applications, collaboration tools, and streaming platforms. Among the most famous digital solutions that use Node.js are Netflix, PayPal, and Amazon Web Services.
To extend the capabilities of Node.js even further, it’s most commonly used in combination with another back-end JS framework called Express.js. Designed to facilitate the development of web applications and APIs, this lightweight, minimalistic framework enables simple and productive web development. An abundance of plugins with well-documented use cases adds to the flexibility and extensibility of the framework, making it perfect for startups and enterprise projects alike.
Today both Node.js and Express.js boast a healthy ecosystem and broad support from the web development community.
