Replacing procedural loops with functions can increase the readability of your program and make it more elegant. It, along with pure functions, makes it easier to reason about and debug your programs. Immutability is a core tenet of functional programming. In frameworks such as Angular and React, you'll actually get a performance boost by using immutable data structures. Recently there has been a growing trend toward functional programming. JavaScript is a multi-paradigm language that allows you to freely mix and match object-oriented, procedural, and functional paradigms. Those first-class functions are what makes functional programming possible in JavaScript. Java technically did not have first-class functions until version 8, however you could simulate first-class functions using anonymous classes. Eich eventually settled on a language that has a C-style syntax (as does Java), yet has first-class functions. Things changed when Eich was told that the new language should be the scripting language companion to Java. Scheme, being a dialect of Lisp, is a functional programming language. When Brendan Eich created JavaScript in 1995, he intended to do Scheme in the browser.

Sophisticated concepts that are deeply rooted into the language tend instead to surface themselves in seemingly simplistic ways, such as passing around functions as callbacks, which encourages the JavaScript developer to just use the language as-is and not worry too much about what’s going on under the hood. Where it takes a pretty in-depth knowledge of a language like C or C++ to write a full-scale program, full-scale production JavaScript can, and often does, barely scratch the surface of what the language can do. While JavaScript is perhaps one of the easiest languages to get up and running with, its eccentricities make solid mastery of the language a vastly less common occurrence than in many other languages. The “Hello World” of JavaScript is so simple that the language is inviting and easy to get comfortable with in early exposure. “JavaScript” is as related to “Java” as “Carnival” is to “Car.” Because JavaScript borrows concepts and syntax idioms from several languages, including proud C-style procedural roots as well as subtle, less obvious Scheme/Lisp-style functional roots, it is exceedingly approachable to a broad audience of developers, even those with just little to no programming experience. The two languages are vastly different in many important ways.

But the name is merely an accident of politics and marketing. Even the name evokes, as Brendan Eich once put it, “dumb kid brother” status next to its more mature older brother, Java. But as a language, it has perpetually been a target for a great deal of criticism, owing partly to its heritage but even more to its design philosophy.

While flickering mouse trails and annoying pop-up prompts may be where JavaScript started, nearly two decades later, the technology and capability of JavaScript has grown many orders of magnitude, and few doubt its importance at the heart of the world’s most widely available software platform: the Web.

I’m sure you noticed, but “JS” in the book series title is not an abbreviation for words used to curse about JavaScript, though cursing at the language’s quirks is something we can probably all identify with! From the earliest days of the Web, JavaScript has been a foundational technology that drives interactive experience around the content we consume.
