# Disallow Symbol Constructor (no-new-symbol)
|
|
|
|
`Symbol` is not intended to be used with the `new` operator, but to be called as a function.
|
|
|
|
```js
|
|
var foo = new Symbol("foo");
|
|
```
|
|
|
|
This throws a `TypeError` exception.
|
|
|
|
## Rule Details
|
|
|
|
This rule is aimed at preventing the accidental calling of `Symbol` with the `new` operator.
|
|
|
|
## Examples

|

|
|
|
|
var foo = new Symbol('foo');
|
|
```
|
|
|
|
Examples of **correct** code for this rule:

|
|
/*eslint-env es6*/
|
|
|
|
var foo = Symbol('foo');
|
|
|
|
|
|
// Ignores shadowed Symbol.
|
|
function bar(Symbol) {
|
|
const baz = new Symbol("baz");
|
|
}
|
|
|
|
```
|
|
|
|
