Eloquent Javascript

With this book, available freely here, I seek to polish the rough edges of my basic grasp on the language in general.

Because I am already comfortable coding Javascript, a lot of the material presented as I traverse the book would not be entirely new to me. If, however, I come across a concept which is somewhat foreign to me, or something which I only ‘barely’ just know, I’d be sure to note them down.

In that sense, the sections which follow are those concepts I described in the previous paragraph, organized by chapters.

Introduction

• First 12 chapters: discusses the javascript language
• Next 7 chapters: discusses web browsers and the way javascript is used to program them
• Final 2 chapters: discusses NodeJs
• In addition to exercises which accompany each chapter, there are five (5) projects to be built VIZ:
  • Delivery robot,
  • Programming Language,
  • Platform game,
  • Pixel Paint program,
  • Dynamic website

Chapters 1 & 2

• Special numbers in Javascript:

  • Infinity
  • -Infinity
  • NaN

• NaN !== NaN

• Short circuit evaluation with || and &&

• Using the break keyword within a loop stops the looping control flow and moves on the next statement in the program, if any.

• the continue keyword within a loop while somewhat similar to break does a fundamentally different thing. It causes causes control to jump out of the current iteration and continue with the next.
