The list of stop words in Elasticsearch is:

a, an, and, are, as, at, be, but, by, for, if, in, into, 
is, it, no, not, of, on, or, such, that, the, their, 
then, there, these, they, this, to, was, will, with

The list of JavaScript reserved keywords is:

abstract, arguments, await, boolean, break, byte, case, 
catch, char, class, const, continue, debugger, default, 
delete, do, double, else, enum, eval, export, extends, 
false, final, finally, float, for, function, goto, if, 
implements, import, in, instanceof, int, interface, let, 
long, native, new, null, package, private, protected, 
public, return, short, static, super, switch, synchronized, 
this, throw, throws, transient, true, try, typeof, var, 
void, volatile, while, with, yield

That means that the overlap is:

for, if, in, this, with

And the remainder of the English stop words is:

a, an, and, are, as, at, be, but, by, into, is, it, no, 
not, of, on, or, such, that, the, their, then, there, 
these, they, to, was, will

Why does this matter? It matters when you're writing a search engine on English text that is about JavaScript. Such as, MDN Web Docs. At the time of writing, you can search for this because there's a special case explicitly for that word. But you can't search for for which is unfortunate.

But there's more! I think we should consider certain prototype words to be considered "reserved" because they are important JavaScript words that should not be treated as stop words. For example...
