JavaScript glossary on demand (JavaScript glossary on demand)
JavaScript glossary on demand
a mini guide to modern JavaScript programming through common terminology explanation
About the Book
Using an innovative and unusual approach in the programming field, this book could somehow be compared to a waterfall: it starts quietly, by describing simple basic terms, and then accelerates until it covers most modern features towards the end.
Rather than explaining every part of the JavaScript programming language by generic topics, this book approach is to explain technical words "on demand" when needed, in order to complete simple to complex tasks.
Being a compact book I recommend you do a quick read-through it first, and once completed, go back to any specific words, so that every term is clear, and every example understood.
