Why does the time turn 0 everytime I run the code?

Question

var time = 0;
setInterval(function() {
time++
localStorage.setItem("t", time);
document.getElementById("a").innerHTML = localStorage.getItem("t");
}, 1000)

Answer 1

let time = localStorage.getItem("t") || 0; // check if "t" exists in localStorage, if true, assign the value to time, else assign 0 to it

Answer 2

VCoder Thank you for the help. The code is working perfectly now

Answer 3

Simply because properties in the localStorage will remain permanently and when you run the code, you set "t" to time which is equel to 0 at the starting of the code, to fix this, just replace the time variable definition by this : let time = localStorage.getItem("t") || 0;

Answer 4

VCoder what should I do so that the time doesn't restart to 0 and instead start from where it was when I close the browser

Answer 5

When you say the "time", you mean here "t" of localStorage, right ?

Answer 6

time is used to display the time
