Is `java` a reserved keyword in JavaScript?

Question

I noticed that several JavaScript IDEs (e.g. Sublime) show a javasyntax highlighted word as a reserved keyword.

Older versions of Firefox have problems with the java function.

function java() {
    alert("This function can not be called");
}

Is this really a keyword? If so, what is it for?

According to this: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Reserved_Words

No, this is not a reserved word.

Taking and running your function in the browser console confirms this.
