Summary of Learning Functional Programming with JavaScript - Anjana Vakil - JSUnconf

00:00:00 - 00:25:00

Anjana Vakil explains how she learned functional programming in JavaScript and how it can be used to write safer and more maintainable code. In functional programming, everything is expressed in terms of functions, which can be difficult to think about at first. However, using pure functions and higher-order functions can make the code more modular and easier to read.

• 00:00:00 Anjana Vakil, a recent English teacher turned software developer, explains how she learned functional programming in JavaScript and how it can be used to write safer and more maintainable code.
• 00:05:00 In functional programming, you want to express everything in terms of functions. This can be difficult because you have to think about the flow of data through the program instead of thinking about objects and how they interact. One way to ease into functional programming is to use pure functions that don't have any side effects. Higher-order functions allow you to pass functions as inputs to other functions, which can make code more modular and easier to read.
• 00:10:00 This video introduces the concept of higher-order functions and shows how they can be used to avoid common programming mistakes. The video also demonstrates how to use a higher-order function to replace an item in an array.
• 00:15:00 The video explains how functional programming can be useful for avoiding headaches and bugs when working with data. It covers the concept of immutable data structures and persistent data structures, and demonstrates the usefulness of these structures by showing how they can be used to change and reuse a single part of an array while not having to make a new copy.
• 00:20:00 In this talk, Anjana Vakil explains the basics of functional programming with JavaScript. She covers topics like immutability, side effects, and pure functions, and recommends a gentle introductory article on the subject. She also provides links to two popular functional programming libraries, Mori and Immutable.js. Finally, she answers a few questions from the audience.
• 00:25:00 This female speaker talks about her personal experiences with different programming paradigms, and how they don't necessarily have to be mutually exclusive. She also talks about the Map function not working, and how it's probably because of concurrent execution. Finally, she speaks about the code of conduct and how it would be against the rules to discuss Concurrency outside of a small room.
