javascript - making a function that pulls all number from an array divisible by 3 -

var array = [3, 4, 6, 5, 9, 10, 21];  var divthree = [];  var lovethethrees = function (array) {   (i = 0; = array.length; i++) {     if (array[i] % 3 === 0) {       amount.push(divthree[i]);     }   } } 

i learning javascript , having bit of trouble function. can feel im close cant figure out im doing wrong.

there different ways of going (as evidenced other answers here), bug in code posted i = array.length resetting value of i. you'll want use < instead. need push proper array.

var array = [3, 4, 6, 5, 9, 10, 21];  var divthree = [];  var lovethethrees = function (array) {   (i = 0; < array.length; i++) {     if (array[i] % 3 === 0) {       divthree.push(array[i]);     }   } }
