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.

# Node
A <strong>node</strong> can be considered a DOM tree element. Let's define a production rule that generates simple DOM elements that do not have any attributes. To do so, we need to analyze element tags. A **tag** is a sequence of a `LESS_THAN_SIGN` character followed by a value (any number of characters), followed by `SLASH` and `GREATER_THAN_SIGN` characters. Additionally , we need to use the `separator` rule before and after the `value` rule. Below is the implementation of the `node()` method.

> Note: We can enter any string value as an input at the bottom of the widget to run the code.
