JavaScript intro

Introduction

I created an introduction to JavaScript video at https://youtu.be/33Xmn5rnisc.

In the video I walked thru the a_js_intro.js file.

The a_js_intro.js script ends up covering a lot of topics!

submenu : setHeader, addItem, show
keyboard : text (first param is # of bytes to allocate, including null terminator)
storage : exists
usbdisk : start, wasEjected, stop
textbox : setConfig, emptyText, addText, show, isOpen
gpio : init, read
badusb : setup, isConnected, press, println, quit
subghz : transmitFile
let, = (assignment), for (loop)
require, print, delay, parse_int, __dirpath
Strings, numbers, booleans
Arrays, .length
+ (adding), i++ (increment by 1), ! (not)
if, else if, === (compare equal), !== (compare not equal)
calling functions, defining functions, return

At the end of the video I ran widget.js to summarize what we learned.
