I want to implement a countdown function outside is scope but I could not access its value in the global scope,I’ve tried a few logic but couldn’t decode it so I thought I should throw it here .

Here’s the code :



let countdownInterval; // Declare the variable in the global scope
let countdown duration = null;

if (ABC) {
// Start a five-minute countdown (300,000 milliseconds)
countdownduration = 300000; // Set the value when the countdown begins

countdownInterval = setInterval(function() {
countdownduration -= 1000; // Decrease by 1 second

if (countdownduration <= 0) {

clearInterval(countdownInterval);

console.log("Five-minute countdown is over!";
} else {
Console.log(“xyz “);
}
}, 1000); // Run the countdown every second (1000 milliseconds)
}

// I want to use it outside its scope like this
if (countdownduration < 280000) {
// Countdown is less than 280,000 milliseconds
Logic xyz
}

How can I make the countdown duration value be available in the global scope pls ?

Use var ..

var item;

If na React, u use state..

Post the code somewhere where it's readable to get better replies.

Post a screenshot of your code

Please post a screenshot of the code, writing it on Nairaland can make it very confusing and difficult to read.

var in 2023 when "let" is available?

Bar and let are two diff things na..

Ok oo. Since you still use var when declaring variables in 2023, I'm sure you also know nothing about arrow functions and spread operators. "const" may also sound strange to you.

Oga just get up..

We should be bragging about programming knowledge, instead we should brag about how many apps we have successfully lunched into the market..


What’s wrong with var?

Wetin be arrow funcs?

Wetin be spreed operator?

These are baby things..



What’s wrong with var?

Var has it own work in JS, go learn..

Next JS devs still use var in 2023...

Be humble

Sit down..

I no dey drag or brag about knowledge of programing... The goal is to have my own products in the market...

This is my last reply to you..

You will find this code in the next/dist folder -> dev

Lol. This one dey open node modules to show me var . Var is not even the solution to the op's question.

Bros be calming down var and let are not the same ,people are still using var and will continue using it till the kingdom come , yes it might not be the solution here but var is still a thing

You know nothing..

U no humble.


Then give him the solution to the problem..

You are one of those new programmers enchanted by basic things..

I Dey use React… Arrow function na norms for dia..

You just disgrace ya self… You wia trying to rubbish me, abi?

Still waiting for ya second project…

Na calculator things be ur fancy, na calculator Zuck take blow?

Well whatever you do don't use var

const and let are the new kids on the block.

Doesn't mean var is obsolete

It's like saying one shouldn't use

function foo(){}

Because

const foo = ()=>{}

Exist

It's not the same thing. People might have a solid reason for using functions foo(). Like, it supports hoisting. It also holds value of this keyword accurately, unlike arrow functions. Var is discouraged against because of security risk and unpredictability it introduces to codes.

Many ways to do same thing with JavaScript it's annoying.


I also believe they should once and for all remove == comparison and let us use ===instead

== Is pointless

== is not pointless, as you could use it to compare primitive values in JavaScript. Not everyone needs strict equality, but i get your point.

Then var is not pointless

Since not everyone needs strict variable declaration

Well true if they want buggy code

You probably shouldn't be using any npm package since they consist of infinite var declr
