comment header in JavaScript (and TypeScript):
* The HelloWorld program implements an application that
* simply displays "Hello World!" to the standard output.

go over how to install Standard, to fix all your code style errors:
bun install ts-standard --save-dev
bun ts-standard ./*.ts
we will not be adding the GitHub Super Linter this year
odd TS errors that do not show above!
Daily Assignment
Daily Assignment
create the "Hello, World" program, going through the complete design and coding process!
ensure you are in the correct directory !!!
./ICS4U/Intro/Intro-06
run the style checker and fix any mistakes
add in design document (flowchart)
push changes back to GitHub

go over Sun's vs Google's style check for Java
we will be using mr-coxall_checks.xml (see below)
a combination of both, with 2 spacing for Java indenting and super strict on almost everything!
java comment header looks like:
