javascript - make something happen every 1 second? -


i challenging myself creating pomodoro timer. i'm having trouble making timer count down automatically... far thinking of using loop although not count down 59..58..57.. on screen. question can make slower...

i have if/else statement allow go 59 - 0 reset 59 again. 

if (s >=0 && s < 10 ) {     $("#second").html("0"+s);     s-- } else if ( s <= 0) {     s = 59; } else {     $("#second").html(s);      s-- } 

function runtimer() {    let count = 59      setinterval(() => {      console.log(count)      count--      if (count < 1) count = 59    }, 1000)  }    runtimer()
