Get index position from array using .each()

Question

How do I retrieve the index position of each element?:

$(myArray).each(function() {
 console.log( ...this.indexOf()?.... )
}

FYI .each() should be used only for jQuery object relative to DOM nodes, here you should use: $.each(myArray, function(index){console.log(index);}) — A. Wolff

Read the docs. The first argument to your callback is the index.

So:

$(myArray).each(function(index,item) {
    console.log(index);
});

Side note: Array.forEach takes it's arguments in the opposite order (item first, then index) which, IMHO, feels more natural. I have no idea why jQuery ended up putting the arguments that way around.

You will get the index of the current item as the first argument to the callback function of $.each()

$(myArray).each(function(i) {
    console.log(i);
})

Demo: Fiddle
