This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The replace() method of the DOMTokenList interface replaces an existing token within a given list by a new one.
tokenList.replace(oldToken, newToken);
console.log(document.documentElement.classList.contains("_mdntest")); //false
console.log(document.documentElement.classList.contains("_mdntest2")); //false
document.documentElement.classList.add("_mdntest");
document.documentElement.classList.replace("_mdntest", "_mdntest2");
console.log(document.documentElement.classList.contains("_mdntest")); //false
console.log(document.documentElement.classList.contains("_mdntest2")); //true
