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.
