Reminder of git commands
See all remotes ....................... git remote -v
Fetch a specific remote ............... git fetch <remote name>
Compare remote with local files ....... git diff --name-only remotes/<remote name>/master
Compare remote with main repo ......... git diff --name-only master remotes/<remote name>/master
Squash commits ........................ git rebase -i <after this commit>
Squash commits into initial commit .... git rebase -i --root
Force submit after squashes ........... git push origin +master
Replace "pick" with "reword" to change the commit message
Replace "pick" with "squash" to combine a commit with the last "pick" commit

Example of Javascript pass by value side effects
// Function to change the passed in variable
testFn0 = obj => { obj = {}; }
// Function to change level one variable
testFn1 = obj => { obj.b = 999; }
// Function to change level two variable
testFn2 = obj => { obj.b.b = 999; }
// Directly changing the passed in variable should not affect it
