Unbox a boxed JS primitive value. This module works cross-realm/iframe, does not depend on `instanceof` or mutable properties, and works despite ES6 Symbol.toStringTag. |
|
|
|
## Example |
|
|
|
```js |
|
var unboxPrimitive = require('unbox-primitive'); |
|
var assert = require('assert'); |
|
|
|
assert.equal(unboxPrimitive(new Boolean(false)), false); |
|
assert.equal(unboxPrimitive(new String('f')), 'f'); |
|
assert.equal(unboxPrimitive(new Number(42)), 42); |
|
const s = Symbol(); |
|
assert.equal(unboxPrimitive(Object(s)), s); |
|
assert.equal(unboxPrimitive(new BigInt(42)), 42n); |
|
|
|
// any primitive, or non-boxed-primitive object, will throw |
|
``` |
|
|
|
## Tests |
|
Simply clone the repo, `npm install`, and run `npm test` |
