Is this an ES6 Symbol value?
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
```js
|
||
|
|
var isSymbol = require('is-symbol');
|
||
|
|
assert(!isSymbol(function () {}));
|
||
|
|
assert(!isSymbol(null));
|
||
|
|
assert(!isSymbol(function* () { yield 42; return Infinity; });
|
||
|
|
|
||
|
|
assert(isSymbol(Symbol.iterator));
|
||
|
|
assert(isSymbol(Symbol('foo')));
|
||
|
|
assert(isSymbol(Symbol.for('foo')));
|
||
|
|
assert(isSymbol(Object(Symbol('foo'))));
|
||
|
|
```
|
||
|
