Cheat sheet: JavaScript Array methods

Deriving a new Array from an existing Array:

['■','●','▲'].slice(1, 3)           ['●','▲']
['■','●','■'].filter(x => x==='■')  ['■','■']
    ['▲','●'].map(x => x+x)         ['▲▲','●●']
    ['▲','●'].flatMap(x => [x,x])   ['▲','▲','●','●']

Using <details> in GitHub

Suppose you're opening an issue and there's a lot noisey logs that may be useful.

Rather than wrecking readability, wrap it in a <details> tag!

Bash alias to recursively delete Dropbox conflicted files
alias rmdbc="find . -name *\ \(*conflicted* -exec rm {} \;" # recursively delete Dropbox conflicted files
# and/or (smart idea from Gordon Fontenot)
alias rmdbcsafe="find . -name *\ \(*conflicted* -exec mv {} ~/DropboxConflicts/ \;" # recursively move Dropbox conflicted files to temp folder
# or... via TJ Luoma
alias rmdbctrash="find . -name *\ \(*conflicted* -exec mv -v {} ~/.Trash/ \;" # recursively move Dropbox conflicted files to Trash
# More advanced idea combining ideas from @modernscientist and @GFontenot would be
# Hazel or launchd script to move conflicted files to temp folder once a day, and Hazel or launchd script to delete files older than [x]
# Or schedule TJ's idea of moving to Trash and skipping intermediate folder while still maintaining the ability to review
# hmmmm...
