from chat:

replacing strings literally in JS is actually pretty not straightforward. Worse, it will work in like 99% of cases until it doesn't. See:

const replaceWith = 'Dollar: \'$\');';
console.log('REPLACE'.replace('REPLACE', replaceWith));

this prints Dollar: '); ... note the missing dollar sign ... because the replace function is "regex-aware" even if the first parameter is not a regex ...

only valid for $' and $`. the others ($0, $1) don't work

so you must do this:

'REPLACE'.replace('REPLACE', () => replaceWith);

After auditing all our usages of String.prototype.replace, I only found this one instance where it could theoretically be problematic.
