How to replace all characters in a string?

I have a string that is passed by parameter and I have to replace all occurrences of it in another string, ex:

function r(text, oldChar, newChar)
    return text.replace(oldChar, newChar); // , "g")

The characters passed could be any character, including ^, |, $, [, ], (, )...

Is there a method to replace, for example, all ^ from the string I ^like^ potatoes with $?


function r(t, o, n) {
    return t.split(o).join(n);
