How to create a countdown seconds timer in TypeScript

Answer 1

function countdown(seconds: number) {
    console.log("Total time: " + seconds + " seconds");

    let interval: number = setInterval(() => {
        seconds--;
        console.log("Time remaining: " + seconds + " seconds");

        if (seconds <= 0) {
            clearInterval(interval);
        }
    }, 1000);
}

let sec: number = 5;

countdown(sec);


    
/*
run:
     
"Total time: 5 seconds" 
"Time remaining: 4 seconds" 
"Time remaining: 3 seconds" 
"Time remaining: 2 seconds" 
"Time remaining: 1 seconds" 
"Time remaining: 0 seconds"
        
*/
