Jackal Reactive

The 'every' function creates a reactive interval. It executes a block of code repeatedly at a specified millisecond interval.

let counter = 0

every(1000) {
    counter++
    println(counter)
}

The 'until' keyword acts as a reactive listener that triggers a callback once a specific condition is met, effectively halting or responding to reactive streams.

until (counter >= 5) {
    println("loop stop")
}
