Use JavaScript to place cursor at end of text in text input element

Question

What is the best way (and I presume simplest way) to place the cursor at the end of the text in a input text element via JavaScript - after focus has been set to the element

Answer 1

I just found that in iOS, setting textarea.textContent property will place the cursor at the end of the text in the textarea element every time. The behavior was a bug in my app, but seems to be something that you could use intentionally.
