** Dom core vs dom HTML spec
|
||
|
|
This would have been helpful in the previous lesson, though I did manage to figure out myDocumentImage.src does work. I actually couldn't find anything about the core style when searching around.

** Selecting all elements
|
||
|
|
It's easy to select all the elements of a specific type and put them into an array. I could see this being useful to do something like grabbing all the IMG elements and adding some sort of default alt text if the HTML developer forgot to add them.

** We can toggle classes easily
|
||
|
|
A simple toggle command can remove and activate classes quickly and easily

** Easy to swap classes
|
||
|
|
We can set a click event to a header to swap classes for it's content. One class hides everything below, a second, reveals it.
|

|
|
** Lot's of JavaScript seems here seems to revolve around swapping.
|
||
|
|
That is, we want to make boxes get checked, boxes get focus, expand/contract headers, etc...
|
||
|
|
Largely we just want to swap around CSS elements.
|
||
|
|
If that's all what the majority of JavaScript in the wild did/does, I think it might not be so bad. But... that's clearly not the case.

Why would I use querySelector instead of getElementBy{Id,Name,Class}? The best I can tell is that it's more generic and allows us to use the standard way of grabbing things (using a "#", for example, to grab an id instead of its own function). If that's the case, perhaps I should start using it. I do enjoy less keywords in my programming.

I'd like to add, this lesson's lecture would have helped a lot for the last unit. ZyBooks has a way of being a bit brain melting, this lecture would have helped a lot on knowing where to start with the labs last lesson. Now, to be clear, I'm not having much trouble with last weeks labs, I do pretty well at researching what I need to know, but I still think this video would be valuable for last week's lesson as well.
