attempt-statement

const attempt = require('attempt-statement')
attempt(() => {
  consoe.log('I misspelled console')
}).rescue((error) => {
  console.log('Error: ' + error)
}).else(() => {
  console.log('No error yay')
}).ensure(() => {
  console.log('This will always be run')
}).end()
// Output:
// Error: ReferenceError: consoe is not defined
// This will always be run

equivalent to:

let error = false
try {
  consoe.log('I misspelled console')
} catch(error) {
  console.log('Error: ' + error)
  error = true
}
if (error === false) {
  console.log('No error yay')
}
console.log('This will always be run')

there is no built in way in javascript to achieve the else behavior so attempt-statement is the way to go.
