I can't any example of this after being unable to puzzle out how it would work on my own.

All I want to do is take a string which has been assigned to a value, and use that as the replace match string for all matches.

var replacement = 'i';
var text = 'tieiam';

text = text.replace(replacement, '');  // 'teiam'

text = text.replace(/tieiam/g, ''); // 'team'

How do I use them together??

What you want is to use the RegExp object:

text = text.replace(new RegExp(replacement, 'g'), '');

Simple example of it in action.
