To implement a countdown timer that updates every second, you can use the setInterval() method. Below is how you can modify your code to achieve this:
Steps
Declare the secsLeft Variable Ensure you have a variable named secsLeft declared at the top of your file. This variable will hold the remaining seconds for the countdown.
Insert the setInterval() Command Directly after declaring secsLeft, add the following command to repeatedly call the countdown() function every second and store the interval ID in the clockId variable.
Code Example
// Declare secsLeft variablelet secsLeft = 60; // Example: 60 seconds for countdown// Use setInterval to call countdown() every secondlet clockId = setInterval(countdown, 1000);// Define the countdown functionfunction countdown() {if (secsLeft > 0) {console.log(`Time left: ${secsLeft} seconds`);secsLeft--; // Decrease seconds left} else {clearInterval(clockId); // Stop the timer when it reaches 0console.log("Countdown complete!");}}Copied!âś•CopyExplanation
