// no args
const args = process.parseArgs()
// node foo.js
// { _: [] }
// node foo.js something
// { _: ['something'] }

// flags are default, strings can be specified:
// node foo.js --foo hello --bar
// {_: [], foo: 'hello', bar: true}
const args = process.parseArgs({
  strings: ['foo', 'a']
})

// Better property name?
requiresValue?
wantsValue?
prefersValue?
takesValue?

// without strings option:
// {_:['hello'], foo: true, bar: true}

// node foo.js --bar
// then result: {_: [], bar: ''}
const args = process.parseArgs({
  strings: ['bar']
})

// or

// maybe, this might be V2:
const args = process.parseArgs(someOtherArrayOfArgs, {
  strings: ['foo', 'a']
})

// Negative numbers are kind of annoying and we're
// trying to think it through:

// add -- -9 -1 // -9, -8
// grep -r -99999 ./foo

// result:

{
  _: ['-9', '-1']
}

// Stop parsing, e.g., npm test -- --grep="some suite"
// foo.js --foo -- --bar --apple
