promiseDelay

函数多次执行的场景下，设置时间间隔限制 Set the time interval limit when the function is executed multiple times

const { promiseDelay } = require('prefer-delay');

console.log('start\t', Date.now());
const print = (index: number) => console.log(index, '\t', Date.now());
const delayFn = promiseDelay(print, 1000);
delayFn(1); // expect time: 0
delayFn(2); // expect time: 1000
delayFn(3); // expect time: 2000
delayFn(4); // expect time: 3000
delayFn(5); // expect time: 4000
setTimeout(() => {
  delayFn(6); // expect time: 5000
}, 4500);
setTimeout(() => {
  delayFn(7); // expect time: 6500
}, 6500);

print:

const { delay } = require('prefer-delay');

(async () => {
