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()

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
