JavaScript’s power and flexibility are shown through its wide array of libraries and frameworks, which include Angular, Node.js, React, and more. Each takes different approaches to empower the various goals of software engineers.

In this course, you’ll be introduced to the various processes of these unique frameworks as you develop a new open-source solution: Assma.js. You’ll become acquainted with compilation theory before defining logical operators. Next, you’ll delimit functions by creating production rules and define the elements of the programming language, including the syntax and semantics in the framework. You’ll finalize the core of the framework using DOM and tree structures before bundling the packages into a plugin component to manage future projects.

By the end of the course, you’ll have a deep understanding of core functions, design theories, and the creation of JavaScript frameworks from conception to deployment.

# Libraries
Let's look at examples of libraries that are often used when building applications based on JavaScript frameworks.

## HTTP
To make things easy with asynchronous requests, some frameworks provide wrappers around the `XMLHttpRequest` object or <strong>API Fetch</strong>. An alternative approach for asynchronous requests is theor API Fetch. In this section, we'll learn to create a simple library for HTTP that provides easy methods to deal with requests. First, create an object with a predefined setter that takes a request as an argument. Below is an example of a `Request` object structure, we can create additional attributes or rename the existing ones:
