Download or read book JavaScript Optimizing Native JavaScript written by Robert Etheredge and published by MiraVista Press. This book was released on 2017-03-02 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: JavaScript has become the most popular programming language in the world. It has attained that position by being easy to use and powerful in its capabilities. It wasn't always that way but today it can be used to build virtually any application you desire. With the addition of HTML5 and CSS3, it allows for wonderfully animated and powerful web sites and applications without having to use other technologies such as Adobe Flash. JavaScript has also become much more standardized across the multiple browsers in use today. With the recent proliferation of libraries and frameworks that many developers use, the focus has shifted towards these new tools, but they still rely on native JavaScript. And these libraries and frameworks can greatly increase the size of your code as well as slowing down performance. This book covers best practices for coding in straight JavaScript as well as pointing out many areas for optimization. The goal is to help programmers produce smaller and faster JavaScript applications. Even programmers using frameworks and libraries can benefit from understanding the performance trade-offs they make when using those tools.

Download or read book How JavaScript Works written by Douglas Crockford and published by Virgule-Solidus. This book was released on 2018-10-18 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Douglas Crockford starts by looking at the fundamentals: names, numbers, booleans, characters, and bottom values. JavaScript’s number type is shown to be faulty and limiting, but then Crockford shows how to repair those problems. He then moves on to data structures and functions, exploring the underlying mechanisms and then uses higher order functions to achieve class-free object oriented programming. The book also looks at eventual programming, testing, and purity, all the while looking at the requirements of The Next Language. Most of our languages are deeply rooted in the paradigm that produced FORTRAN. Crockford attacks those roots, liberating us to consider the next paradigm.He also presents a strawman language and develops a complete transpiler to implement it. The book is deep, dense, full of code, and has moments when it is intentionally funny.
