// Grab the original element
var original = document.getElementsByTagName("noscript")[0];
// Create a replacement tag of the desired type
var replacement = document.createElement("span");
var i;
// Grab all of the original's attributes, and pass them to the replacement
for(i = 0, l = original.attributes.length; i < l; ++i){
var nodeName = original.attributes.item(i).nodeName;
var nodeValue = original.attributes.item(i).nodeValue;
replacement.setAttribute(nodeName, nodeValue);
}
// Persist contents
replacement.innerHTML = original.innerHTML;
// Switch!
original.parentNode.replaceChild(replacement, original);

Answer 1

You have a comma after i = 0, <========
it should be semicolon.
Another issue is declaring l = original.attributes.length you don't need the variable l
just use it as for(i = 0; i < original.attributes.length; ++i){
if you still wanna use a forEach you can do it as:
original.attributes.forEach(element => {
var nodeName = element.nodeName;
var nodeValue = element.nodeValue;
replacement.setAttribute(nodeName, nodeValue);
});

Answer 2

thanks for your answer, i got Uncaught TypeError: original.attributes.forEach is not a function
function Switch() {
var original = document.getElementsByTagName("noscript")[0];
var replacement = document.createElement("span");
original.attributes.forEach(element => {
var nodeName = element.nodeName;
var nodeValue = element.nodeValue;
replacement.setAttribute(nodeName, nodeValue);
});
// Persist contents
replacement.innerHTML = original.innerHTML;
// Switch!
original.parentNode.replaceChild(replacement, original);
}
