Anthony Alicea is a US software engineer and educator best known for JavaScript: Understanding the Weird Parts — one of the canonical paid courses on JavaScript's underlying mental model (execution context, scope chain, prototype inheritance, the call stack) and one of the most widely-recommended deep-dives into the language for developers ready to move past surface syntax.
The course catalog extends into TypeScript (the deep type-system material rather than the syntax tour), React, Node.js, and the broader JavaScript ecosystem. The teaching style is unusually rigorous about the language fundamentals — Anthony's courses are taught at the level of someone who wants you to understand why JavaScript behaves the way it does, not just memorise the rules.
The CourseFlix listing under this source carries 7 Anthony Alicea courses spanning that range. Material is paid and aimed at developers ready to deepen their craft on the JavaScript / TypeScript stack.
