What mechanism does this throttle implementation use to control execution frequency?
function throttle(func, limit) {
let inThrottle;
return function(...args) {
if (!inThrottle) {
func.apply(this, args);
inThrottle = true;
setTimeout(() => inThrottle = false, limit);
}
};
}
This throttle implementation uses a specific control mechanism: 1) It uses a boolean flag (inThrottle) to track whether we're in the throttle period, 2) The flag prevents any execution during the throttle interval, 3) setTimeout is used to reset the flag after the specified limit, 4) This creates a time window during which subsequent calls are ignored, 5) The pattern ensures exactly one execution per time period if events are occurring, 6) It's a memory-efficient approach using minimal state, 7) The closure preserves the throttle state between calls, 8) This implementation provides predictable execution timing.
