My Leetcode solution: 2725. Interval Cancellation
/**
* @param {Function} fn
* @param {Array} args
* @param {number} t
* @return {Function}
*/
var cancellable = function(fn, args, t) {
fn(...args)
const h = setInterval(() => fn(...args), t)
return function() {
clearTimeout(h)
}
};
/**
* const result = []
*
* const fn = (x) => x * 2
* const args = [4], t = 20, cancelT = 110
*
* const start = performance.now()
*
* const log = (...argsArr) => {
* const val = fn(...argsArr)
* result.push({"time": Math.floor(performance.now() - start), "returned": fn(...argsArr)})
* }
*
* const cancel = cancellable(log, args, t);
*
* setTimeout(() => {
* cancel()
* console.log(result) // [
* // {"time":0,"returned":8},
* // {"time":20,"returned":8},
* // {"time":40,"returned":8},
* // {"time":60,"returned":8},
* // {"time":80,"returned":8},
* // {"time":100,"returned":8}
* // ]
* }, cancelT)
