Douglas Crockford - Create Object Recipe (2014)

Douglas Crockford showed a slide showing how he creates JavaScript objects in 2014.

He no longer uses Object.create(), avoids 'this' and doesn't even care about memory reduction by using prototypes.

https://www.youtube.com/watch?v=bo36MrBfTk4 (skip ahead to 35 mins for relevant section)

Here is the pattern described on the slide:

function constructor(spec) {

Setting up Cmder to use bash by default

Set up cmder to use msysgit / bash by default

  • Install cmder_mini (msysgit is already installed, so no need for full version)
  • In Cmder, open settings: Win + Alt + P
  • Under Startup > Tasks, add a task called {bash} with the following settings:
    • Task parameters (set icon):
      • For Cmder icon: /icon "%CMDER_ROOT%\cmder.exe"
      • For Git icon: /icon "C:\Program Files (x86)\Git\etc\git.ico"
    • Commands (open Git's bash shell):
  • "C:\Program Files (x86)\Git\bin\sh.exe" -l -new_console:d:%USERPROFILE%
