Eloquent JavaScript dives into the JavaScript language to show programmers how to write elegant, effective JavaScript code. Like any good programming book, Eloquent JavaScript begins with fundamentals--variables, control structures, functions, and data structures--then moves on to complex topics like object-oriented programming and regular expressions. This third edition introduces new features covering the 2017 version of JavaScript, such as class notation, arrow functions, iterators, async functions, template strings, and blac k scope. Author Marijn Haverbeke keeps the friendly tone and easy-to-follow explanations that made the original a hit, and he adds new exercises for readers to test their skills. Eloquent JavaScript will have readers fluent in the language of the web in no time, eloquently.
