Supposed that we have this html:

```
<div class="some-class">This is the content</div>
<h2 class="some-class">This is to be replaced</div>

```

In jquery, we can replace the content of the h2 using:

```
$('h2.some-class').html('string to replace');

```

This will replace the h2.some-class without changing content of div.some-class. Now, the current page doesn't have the luxury of using a framework or jquery for this instance - only javascript.

How can we replace that **tag with specific class** using plain javascript without affecting other tags with the same class?
