Douglas Crockford Knihy

JavaScript, having been developed and released in a hurry before it could be refined, has more than its share of the bad parts. This book scrapes away these bad features to reveal a JavaScript subset that's more reliable, readable, and maintainable than the language as a whole-a subset you can use to create extensible and efficient code. (back cover copy)

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.
