Status Updates From JavaScript: The Definitive ...

38

It is definitive alright.

Arrays

Properties

Prototypes

“The undefined value represents a deeper kind of absence.” - aaaw, cute.

Object destructuring in detail, looked up but didn’t find an answer to how object destructuring works in TS when using an alias. Niche question for sure, but important

Glossed over object to primitive conversions going over: prefer-string algorithms, prefer-number algorithms, and no-preference algorithms. Apparently prefer-number is used more than a majority of the time when there is no-preference except for in the case of date objects which use prefer-string

Learned some things about text and that some characters are two sixteen bit values, such that a string with a heart would have a length of two whereas a string with the euro character is just a sixteen bit character. Also learned about some string normalization methods that I’d like to play with as well as a quick intro to Symbols which I need to dive deeper I to. There was also some good advice on when to use null

Relearned that strings are immutable in JS, learned about Unicode a bit and that you can include it in variable names but not to trust if it’s normalized, learned about different bases 0o octet 0b binary 0x hexadecimal, and about the BigInt object introduced in 2020 to handle base 64 numbers.

Got through the intro, trying to read cover to cover by the end of January.

Giving the 2020 edition a good old read

It's probably going to take me five years to finish it.

Arrays

getter & setter

Boolean

Date & time & strings ;)

Starting over the definitive guide...

3.8.3

Oh,
(.3 - .2) != (.2 - .1)
Welcome to binary floating-points. I think I understand.

I already found some small cool code snippets.

Uh. So dry. And I have to work on creating a quiz. So far it's an array of objects. May have to look at JavaScript: The Good Parts and Google for help with making the quiz.

Seriously considering skimming/speed reading the if/else/loops/switch-case & arrays sections. I already know how to use them.

Chapter 3 was quite long. Two more chapters to conquer this week.

Part 2 Client Side Javascript - nearly done - ban pami!

Mwahaha! Moar!

I know Kung-Fu. Got to show it to Morpheus now.

This book does clarify a lot of JavaScript peculiarities.

All that SVG and Canvas stuff... Not actually all that much on SVG, but a *ton* on Canvas. But it's not all sinking in--I'll need to come up with a project to dork around with the Canvas APIs and figure them out. Reading alone won't cut it.
