Rough implementation of the JavaScript setInterval function in Swift. Good for JavaScriptCore.
var nextTimerId = 0
var timerRegistry = [Int: Timer]()
let setInterval: @convention(block) (JSValue, Double) -> Int = { (function, interval) in
let timer = Timer.scheduledTimer(timeInterval: interval / 1000.0, repeats: true, action: { (timer) in
function.call(withArguments: [])
})
let timerId = nextTimerId
timerRegistry[timerId] = timer
