Pattern: Use of new with non-constructor globals

Issue: -

Description

The Symbol and BigInt functions are not constructors and will throw a TypeError when used with new. Though they start with uppercase letters like classes, they are functions that create primitives.

Examples

Example of incorrect code:

let sym = new Symbol("foo");
let num = new BigInt(9007199254740991);
let value = new Symbol.for("bar");

Example of correct code:

let sym = Symbol("foo");
let num = BigInt(9007199254740991);
let value = Symbol.for("bar");

// Other constructors are fine
let str = new String("foo");
let obj = new Object();
