Disallows the use of new
operators with built-in Symbol
s.
Symbol
s are created by being called as a function, but we sometimes call it
with the new
operator by mistake. This rule detects such wrong usage of the
new
operator.
Invalid:
const foo = new Symbol("foo");
Valid:
const foo = Symbol("foo");
function func(Symbol: typeof SomeClass) {
// This `Symbol` is not built-in one
const bar = new Symbol();
}
