You could use a function and an object with the replacments.

var string = 'EaEbZcZdZ';

string = string.replace(/[EZ]/g, s => ({ E: 'Z', Z: 'E' }[s]));
console.log(string);

Change all "E" to an unused character in the document, e.g. "$". Change "Z" to "E" and then "$" to "Z".

Replace all E to an unused character (like ¬), then change all Z to E, and finally change all ¬ to Z.
