RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including egna. Try it out:
var { match, lt } = require("egna")
/* Try changing the year to something earlier than 1950 */
let car = async () => ({ make: 'Toyota', year: 1968 });
car()
.match(
{ make: 'Subaru'}, 'Subaru',
{ year: lt(1950) }, car => `Super old ${car.make}`,
{ make: 'Toyota' }, ({ year }) => `Toyota from ${year}`,
_ => {throw 'I dont recognize this car'}
)
.then(console.log)
.catch( (e) => console.log("error: " + e) );
