Discussion on: Getting started with MojiScript: FizzBuzz (part 1)

[Jorge Ramón]

Amazing!

Just one question, does it has a better performance than normal JavaScript for Node.js?

Or it is just for doing functional coding style?

[JavaScript Joel]

Thanks, but you are asking the wrong question!

It functions better than JavaScript.

Look at this JavaScript code. It is complicated to understand the output. This code outputs all give 6's after 1 second.

for (var i = 1; i < 6; i++) {
  setTimeout(() => console.log(i), 1000)
}
// => 6
// => 6
// => 6
// => 6
// => 6

Now look at the MojiScript alternative. This program will output 1 through 5 with 1 second delay between each output. (imports have been excluded for brevity)

const sleepThenLog = pipe ([
  sleep (1000),
  log
])

const main = pipe ([
  ({ start, end }) => range (start) (end),
  map (sleepThenLog)
])

main ({ start: 1, end: 6 })
// => 1
// => 2
// => 3
// => 4
// => 5

Did you notice that? Did we just create an asynchronous map? Shhh. articles coming out on Asynchronous map, filter, and reduce shortly. Stay tuned!
