[@farzamyousuf3354]

please one video in let and const

[@mdnasiransari2039]

Can you help me on that, this question is asked in Deloitte . 1) Write a javascript function which accepts a string containing a pattern of brackets and returns true if the pattern of brackets is correct. Otherwise it returns false. The string of brackets is correct if it satisfies the following conditions: 1. Number of opening and closing brackets are equal. 2. Pattern should not start with closing bracket and end with opening bracket. // )()((()()) -> False // ()((())()) -> truelet string=')()((()())';

[@PIYUSH-lz1zq]

IT CAN BE SOLVED USING STACK . CHECK WITH EVERY OPENING BRACKET WE HAVE CLOSING BRACKET OR NOT

[@shubhaprasadmaharatha9563]

Bina timer se batao bhai

[@keristgamer]

Bro aapko sab code yaad hein kya 😨😨

[@adityaparmar4996]

its a wrong example you are just delaying the function , its not throttling , one should check the time period last function is call const getData = () => { document.getElementById("btn").disabled = false; console.log("Getting data ..."); }; const throttle = (fn, limit) => { let lastExecutionTime = 0; return function (...args) { const currentTime = Date.now(); if (currentTime - lastExecutionTime >= limit) { fn.apply(this, args); lastExecutionTime = currentTime; } }; }; const betterFunction = throttle(getData, 3000); // Attach the throttled function to the click event of a button document.getElementById("btn").addEventListener("click", betterFunction);

[@kumarprashant8476]
