When using array to name input fields in HTML -- how to count array length?

Question

Let's say I have some html that looks like this:

<input type="text" name="myInputs[]"> 
<br>
<input type="text" name="myInputs[]"> 
<br>
<input type="text" name="myInputs[]"> 
<br>

I want to use the length of the myInputs array inside some JavaScript code. How do I extract the length of this array? myInputs.length doesn't seem to work

You have tried accessing it through the form? myform.myInputs.length? — Halcyon

console.log(document.formName.elements["myInputs[]"].length);

document.querySelectorAll("[name='myInputs[]']").length

You can also call querySelectorAll on the form element itself
