 ## replace(str, match, replacement)
 Replace text in a string. `match` can either be a literal string or a regular expression: `replace("hello", "ell", "all")` would produce “hallo”, and `replace("hello", /l/, "b")` would produce “hebbo”.
 
+This function supports an infinite number of replacements, so you can keep adding more, e.g. `replace(str, match1, replacement1, match2, replacement2, match3, replacement3)`
+
 ## json(obj)
 Convert the argument to a JSON string (for debugging purposes).
