The <code>replace</code> filter will format a given string by replacing placeholders.

For example, if you had a string like the one below, and the customer.company name you were referencing was 'John Doe':

```bash
{{"I like %this%."|replace({'%this%': customer.company})}}

will print "I like John Doe."
```
A common use example of the replace filter is:
```bash
|replace("American Express", "AMEX")

will print "AMEX" in place of American Express.
