What You'll Learn
- Identify pure functions and refactor code to eliminate side effects and shared state
- Apply higher-order functions to build declarative, reusable transformations in JavaScript
- Compose modular pipelines using Ramda pipe and compose for clear data transformations
- Use currying and point-free style to create concise functions with partial application
- Debug functional pipelines by inspecting intermediate values with Ramda tap
- Implement sorting and multi-criteria comparators using sortBy, sortWith, ascend, and descend
- Build a functional Wikipedia search UI using Ramda to parse input, fetch JSON, and render results

About this course
WHY I WROTE THIS COURSE
We know the functional programming (FP) hype train's been riding strong the past few years, especially in the JavaScript community. We extol FP in countless books, videos, and blog posts, with no sign of slowing down.
As a result this course isn't to convince you, today's JS developer, of how awesome FP is. I'm simply sharing some popular patterns using Ramda, an FP library that I've blogged on many times.
Before going through them, though, we will lay the groundwork with concepts like pure functions, currying, and point-free style.
You're already doing FP through map, filter, reduce, and Lodash, so why not dive a bit deeper and see if you like it down here?
