Hi,

it's a javascript question but as JS is widely used in o-s-c, could someone tell me how do you call this 3 points "operator (?)" ... in Javascript ? What does it do ?
I will find doc then.

Example

function controlSequence(host, port, address, preArgs, sequence) {

    var i = 0
    var timer = setInterval(()=>{
        send(host, port, '/note', ...preArgs, sequence[i])
        i += 1
        if (i == sequence.length) clearInterval(timer)
    }, 50) // set here the time interval

}

Cheers
