assorted web dev notes

JSON (All Javascript, Javascript Object Notation) replaces AJAX (Asynch Javascript and XML)

JSON parses the object itself, converts object to a String

Asynchronous data can be updated, changed from different servers, urls.

”  ” = = empty string ≠ null, ≠ undefined

universal object.property = function name;

eg.

window.onload = init;

button.onclick = buttonClickHandler;

 

/ = slash or forward slash

\ = back slash (nemonic: the N or the slash in STOP signs

 

/ = root

.. = parent dir or above current dir

../ = sibling dir; same parent

dir name = child dir; below in tree or a subdir
