I only saw the throttle function implementation and it seems incorrect to me. Because just think about it if we make two calls within the delay time, the first call will be invoked immediately and second function will be invoked after the delay.

In most of the videos, they don't explain the reason for adding a particular line of code in custom debounce/ throttle. Thank you for a detailed explanation. Really helps. Cheers!

someone ask me but don't know A web developer is creating code using the JavaScript promise method. Consider the following JavaScript promise function syntax: function makeAPromise (resolve, reject) { resolve(1); setTimeout(resolve, 2000, 2); } let promise = new Promise(makeAPromise); promise.then(alert); What happens to resolve in the second call? The output is 2. The call is ignored. The function will be called in 2 seconds. The call is promised to run.

Hey Piyush bro, I found a small issue with the throttle polyfill. Once I stop clicking the button, at the end we need to make a call to the cb function.

Here's the modified code. lmk if this is right function throttle(fn, delay) { let prevTime = 0; let waitingArgs = null; return function(...args) { waitingArgs = args; const currTime = new Date().getTime(); if (currTime - prevTime >=delay ) { fn(...args); waitingArgs=null; prevTime = currTime; } else { setTimeout(() => { waitingArgs !== null && fn(...waitingArgs); waitingArgs = null; }, delay) } } }

if you use setInvterval, it will keep adding on constant time no matter if you click the button or not.

Problem Statement: Weekday date range picker component Create a date range picker component in React and TypeScript that allows users to select weekdays (Monday through Friday) and prevents them from selecting weekends (Saturday and Sunday). The component should include the following features: ● The component should allow users to select a date range defined by a start date and an end date. Remember that a start date and an end date must be a weekday and should not be a weekend. ● The selected date range should highlight only weekdays and weekends should not be highlighted. ● The user should be able to change the year displayed in the date picker. ● The user should be able to change the month displayed in the date picker. ● The component should include a change handler that returns the selected date range and any weekend dates within that range. As an example, if the range selected is December 1st, 2022, to December 15th, 2022, the returned values should be an array containing the date range as the first element (e.g. [2022-12-01, 2022-12-15]) and an array of weekend dates within that range as the second element (e.g. [2022-12-03, 2022-12-04, 2022-12-10, 2022-12-11]). ● The component should include a prop that allows the user to input predefined ranges, such as the last 7 days or last 30 days. These predefined ranges should be displayed below the calendars. Please refer to the date range picker linked below as an example: rsuitejs.com/components/date-range-picker/#predefined-date-ranges The use of date picker libraries (e.g. react-datepicker) or date libraries (e.g. date-fns, Moment.js, Day.js) is strictly prohibited. sir please a tutorial for this problem
