ES6 Defaults / Overrides Pattern

Combine default parameters and destructuring for a compact version of the defaults / overrides pattern.

function foo ({
    bar = 'no',
    baz = 'works!'
  } = {}) {

First Timers Only website idea

I wrote a blogpost on Medium last week about something I've been doing with my open source project. Check that out first: https://medium.com/@kentcdodds/first-timers-only-78281ea47455

It's had a fantastic response and people are enthusiastic about the idea. In an effort to encourage more projects to participate, I decided to file an issue on the up-for-grabs website repo and ask them if they would be willing to have a section dedicated to projects with first-timers-only issues.

If you checkout that issue, you see that Scott Hanselman has bought the domain firsttimersonly.com and wants to turn it into a one pager about the idea with links/resources/etc.

Advantages compared to using symbols as enum values:

• Enum values are much more customizable. For example, one can have custom prototype and/or instance methods.
• Enum values get two custom properties:
  • name provides direct access to the name of an enum value.
  • ordinal holds a number, the position of the enum value. Useful for some applications.
• One can use instanceof to test whether a value is an element of an enum.
• One occasionally requested feature for enums is that enum values be numbers (e.g. for flags) or strings (e.g. to compare with values in HTTP headers). That can be achieved by making those values properties of enum values. For an example, see enum Mode, below.

Static properties of enums:
