function in Execute JavaScript before change detection

[jawharjob]

Hello and thank you for the wonderful program
I am trying to run a function within the program but it does not work
in Execute JavaScript before change detection
I am not a professional just a student

function removetest(selector) {
    var elements = document.querySelectorAll(selector);
    for (let i = 0; i < elements.length; i++) {
        var element = elements[i];
        element.remove();
       }
}

setTimeout( runtest, 2000);


function runtest() {
removetest('.SP-Iconized__text')
removetest('.SP-LinkList__item')
}

Note: This is a sample example of the function I want to run, but even this example does not work

Error:
Page request from server didnt respond correctly - SyntaxError: Unexpected identifier 'setTimeout' at eval () at UtilityScript.evaluate (:226:30) at UtilityScript. (:1:44)

I'm also getting this error. Here's a simplified example:

function foobar(x) {
    // Non-relevant multi-line function here
}

Array.from(document.querySelectorAll("…")).map(el => el.remove());

I get an SyntaxError: Unexpected token at the Array token. Maybe the issue is with the function statement? If I try:

function foobar(x) {
    // Non-relevant multi-line function here
};
// ↖ Notice the added semicolon

Array.from(document.querySelectorAll("…")).map(el => el.remove());

Then I get SyntaxError: Unexpected token at the ; semicolon.

If I copy-and-paste the entire code into the browser dev tools, it works flawlessly; so I know my code is valid. I even tried copy-pasting into a string and then eval(my_code_as_string), and the browser still thinks it's valid.

After a long troubleshooting time, I think changedetection is having trouble with the function statement. If I replace it with a function expression and assign it to a variable, it seems to work:

var foobar = (function(x) {
    // Non-relevant multi-line function here
});

Array.from(document.querySelectorAll("…")).map(el => el.remove());
