How to loop through array in jQuery

Question

I am trying to loop through an array. I have the following code:

 var currnt_image_list= '21,32,234,223';
 var substr = currnt_image_list.split(','); // array here

Am trying to get all the data out of the array. Can some one lead me in the right path please?

Generic loop:

var i;
for (i = 0; i < substr.length; ++i) {
    // do something with `substr[i]`
}

or in ES2015+:

for (let i = 0; i < substr.length; ++i) {
    // do something with `substr[i]`
}
