Explore functional programming in JavaScript through recursion, currying, mapping, reducing, filtering, and composition. Learn what functional JavaScript means and apply these techniques using ES2015 syntax, variables, types, and functions.
Explore imperative javascript and its historical top-to-bottom style that mutates state, contrasting with functional programming. See a browser example with a button, prompt, and alert that capitalizes words.
Explore how object oriented JavaScript encapsulates data as objects, uses prototypes and methods, and leverages an immediately invoked function expression and strict mode for encapsulated code compared to imperative approaches.
Discover functional style in JavaScript through first-class functions, immutability, and higher-order patterns like map, comparing ECMAScript 5 and ECMAScript 2015 approaches.
Learn pure functions that always return the same result for the same inputs and produce no side effects on external state. They improve testability, readability, and enable memorization.
Master higher order functions in JavaScript, where functions are first class and can be passed, returned, or used as callbacks. Use setInterval and setTimeout as demonstrations.
Explore recursion, a higher order function, by contrasting traditional for and while loops through a factorial example, highlighting readability and state management in JavaScript.
Explore recursion as a clean alternative to while loops by implementing a countdown and a factorial function with a clear terminal condition and stateless design.
Explore recursion's trade-offs, including syntax challenges and memory use, and learn to implement proper tail calls and tail call optimization with a factorial example using a tail-position helper and accumulator.
Currying consolidates similar functions into one base, reducing repetition and maintenance in JavaScript. The greet example shows how this enables flexible greetings and centralized type checks, avoiding duplication.
Show manual currying by building a greet curried function that returns a function awaiting a name, with string type checks. Demonstrate creating related greetings sharing the same code.
Explore deep currying of variadic functions in JavaScript by building a greeting function that customizes every element: greeting, separator, emphasis, and name, through nested function calls and partial application.
Explores currying and partial application in JavaScript, showing how variadic functions challenge fixed signatures and how a partial utility can supply missing arguments without heavy nesting.
Learn currying and robust partial application using well-maintained libraries, addressing missing and optional parameters, argument order, and basic error handling.
Discover how map, reduce, and filter in ECMAScript 5 offer functional alternatives to for loops, enabling cleaner array processing and creation of derived arrays like string lengths.
Use map to create a new array of same length with transformed values, without mutating the original, using a pure getLength function. Treat map as a functor in ECMAScript 5.
Use the reduce method to derive a single value from an array by using a pure function that carries an accumulator and avoids mutating the original array.
Learn how the filter method creates a new array by testing each element against a boolean condition, returning only matches without mutating the original, using pure functions.
Explore map, reduce, and filter in JavaScript, weigh performance against traditional loops, and learn to write clean, maintainable code that can be optimized only when a real bottleneck appears.
Learn to compose functionality in JavaScript by nesting pure functions and using higher-order functions, mastering the order of operations to build complex behavior from simple parts.
Build a new function that combines add 1 and times 2 to show manual composition. Compare longer syntax and compact approaches, then introduce a compose utility to control function order.
Build a simple compose utility that takes two functions, returns a composed function, and demonstrates how order and return types shape results, with tests like add one and times two.
Replace a fragile homegrown compose with a robust library that handles nested and multi-argument inputs. Understand why a library's compose avoids extra arguments and supports variadic functions through clear examples.
Explore practical functional techniques in JavaScript, including pure functions, recursion with terminal condition and tail calls, currying, mapping, reducing, filtering, and composition to write cleaner, state-free code.
Continue your functional programming journey by applying ideas today in existing JavaScript projects, prioritizing pure functions, testability, and maintainability, then refactor for clarity as needed.
