swing-exp v1.0.0

swing-exp

An alternative for the switch statement that can be used expressively. Can only be used to match Strings. Other values will be converted to String.

The swing function always takes two arguments:

• The value to be matched
• An object defining the cases

const swing = require('swing-exp')
const value = 'foo'

console.log(swing(value, {
  foo: 'Hello',
  bar: 'Goodbye'
}))

// => Hello

Define a default case to use when there's no match:

const swing = require('swing-exp')
const value = 'foo'

console.log(swing(value, {
  bar: 'Hello',
  baz: 'Goodbye',
  default: 'Pineapple'
}))

// => Pineapple

Execute (blocks of) statements by providing case methods and calling the return value:

const swing = require('swing-exp')
const value = 'foo'

swing(value, {
  foo () {
    const greeting = 'Hello'
    console.log(greeting)
  },
  bar () {
    console.log('Goodbye')
  }
})() // note the parentheses

// => Hello
