    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Usage

```javascript
var reviveBasePRNG = require( '@stdlib/random-base-reviver' );
```

#### reviveBasePRNG( key, value )

Revives a JSON-serialized pseudorandom number generator (PRNG).

```javascript
var parseJSON = require( '@stdlib/utils-parse-json' );
var randu = require( '@stdlib/random-base-randu' );

var str = JSON.stringify( randu );

var rand = parseJSON( str, reviveBasePRNG );
// returns <Function>
```

For details on the JSON serialization format, see the `.toJSON()` method for, e.g., [`randu()`][@stdlib/random/base/randu].

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var randu = require( '@stdlib/random-base-randu' );
var parseJSON = require( '@stdlib/utils-parse-json' );
var reviveBasePRNG = require( '@stdlib/random-base-reviver' );

// Progress the PRNG state...
var r1;
var i;
for ( i = 0; i < 100; i++ ) {
    r1 = randu();
}

// Serialize the PRNG as a JSON string:
var str = JSON.stringify( randu );

// Revive the JSON-serialized PRNG:
var rand = parseJSON( str, reviveBasePRNG );
if ( rand instanceof Error ) {
    console.error( rand.message );
}

// Generate duplicate sequences...
var r2;
for ( i = 0; i < 100; i++ ) {
    r1 = randu();
    r2 = rand();
    console.log( '%d == %d ? %s', r1, r2, ( r1 === r2 ).toString() );
}
