"Modern JavaScript puts you in the center of an enormously powerful language and ecosystem. As a result, the fundamentals of the language are lastingly important, and there is always more to learn. The core language is magnificently refined and intricate. Mastering universal programming fundamentals like variables, collections, and paradigms gives you the ability to confidently navigate the language. From this base, you can fluently engage with the vast array of client- and server-side tools and platforms that comprise the JavaScript landscape."
"Arrays are simple: let books = ["The Supreme Yoga", "The Transcendent Unity of Religions", "The Tao of Physics"]; We can iterate over this collection using functional programming and an arrow function: books.map(x => x.length); This creates a new array showing the length of some of my favorite book titles. We can use the map operation and siblings like filter and forEach to iterate over the collection without describing the loop imperatively."
JavaScript is a large, evolving language and ecosystem that rewards firm mastery of fundamentals. Core language features are refined and intricate, making fundamentals like variables, collections, and paradigms essential to navigate the language confidently. Collections are commonly modeled with arrays and increasingly with Set objects; functional iteration methods such as map, filter, and forEach avoid imperative loops. Arrow functions provide compact syntax well suited to functional operations. Learning these foundational concepts enables fluent use of client- and server-side tools and platforms and positions developers to leverage modern JavaScript for both programs and career growth.
