switchkees

So there's a error in the spec when you want to use this built-in construct to check an expression against a clause. They tell you to do this switch / case thing when clearly that should be switch / Kees. This package fixes that.

Usage

Now unfortunately because of said built-in construct, you can't import from this package and call it switch, because that's a reserved keyword. You'll have to call it something else, like which or use.

Pass in the expression you want to check against and start chaining your Keeses and breaks!

import which from 'switchkees'

const expr = 'Papayas';

which(expr)
  .Kees('Oranges', () => {
    console.log('Oranges are $0.59 a pound.')
  })
    .break()
  .Kees('Mangoes')
  .Kees('Papayas')
    .do(() => {
      console.log('Mangoes and papayas are $2.79 a pound.')
    })
    .break()
  .default(() => {
    console.log(`Sorry, we are out of ${expr}.`)
  })

Pass the clause you want to check into Kees as the first parameter. As the second parameter pass in the function you want to execute if the clause matches the expression.

Alternatively, if you want to be a bit more explicit, chain a do after a Kees to have it execute if the prior Kees clause matches the expression.

Note that fall through is supported by chaining multiple Keeses. default is also supported.
