# no-new-native-nonconstructor

> Disallow `new Symbol()` and `new BigInt()`

`Symbol` and `BigInt` start with a capital letter but aren't constructors. `new Symbol("id")` and `new BigInt(10)` throw a `TypeError` when they run. Call them without `new`.

This rule is on by default in JavaScript files. It's off in TypeScript files, where TypeScript reports the same mistake.

## Configure

On by default as an error. To turn it off:

```
