Is there a faster way of writing OR operator?

Question

Is there a faster way of writing this?

if ($(\'#id\').val()==7 || $(\'#id\').val()==8 || $(\'#id\').val()==9){
    console.log(\'value of #id is 7, 8, or 9!\         


        

Answer 1

I just added this one to the jsperf: the in operator. The value in every key:value (e.g. 7:7) pair is irrelevant here.

if ($('#id').val() in {7:7, 8:8, 9:9}) {
  console.log('value of #id is 7, 8, or 9!')
};
