How can I use querySelectorAll() to select all input elements of a specific type (e.g., all text inputs or all checkboxes) within a specific form?

You can use `querySelectorAll()` in combination with a CSS attribute selector to select all input elements of a specific type within a specific form. Here's how you can do it:

1. Give your form an `id` attribute so that you can easily target it. For example, `<form id="myForm">`.
2. Use the `querySelectorAll()` method on the form element and specify the input type using the attribute selector `[type=""]`.

Here's an example:

HTML:
```html
<form id="myForm">
<input type="text" name="textInput1">
<input type="text" name="textInput2">
<input type="checkbox" name="checkbox1">
<input type="checkbox" name="checkbox2">
</form>
```

JavaScript:
```javascript
// Select the form element by its id
const form = document.getElementById('myForm');

// Select all text inputs within the form
const textInputs = form.querySelectorAll('input[type="text"]');
console.log(textInputs);

// Select all checkboxes within the form
const checkboxes = form.querySelectorAll('input[type="checkbox"]');
console.log(checkboxes);
```

In this example, the `textInputs` variable will hold a NodeList of all text input elements within the form, and the `checkboxes` variable will hold a NodeList of all checkbox elements within the form.
