Sharepoint: How to enable a field when a check box is selected on new item form?

Question

In Sharepoint, I need modify a new item form of a list to make a field visible/invisible when a check box is selected:

For example: There is a checkbox field called "Is XYZ affected?"

When a user selects this field, it will make a hidden field visible "Impact details:"

If "Is XYZ affected?" field is not checked, then "Impact details:" field is invisible.

This is easy to do it in html using javascript, how do I do it on Sharepoint?

Thanks!
