    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>

<section class="notes">

## Notes

-   The [symbol][mdn-symbol] is only supported in environments which support [symbols][mdn-symbol]. In non-supporting environments, the value is `null`.
-   When calling `String.prototype.replace` and `String.prototype.replaceAll` and the `pattern` argument is an object with a `[ReplaceSymbol]()` method, this method is called with the target string and replacement as arguments.

## Examples

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

```javascript
var defineProperty = require( '@stdlib/utils-define-property' );
var ReplaceSymbol = require( '@stdlib/symbol-replace' );

function replace( str, replacement ) {
    return replacement;
}

var obj = {};

defineProperty( obj, ReplaceSymbol, {
    'configurable': true,
    'value': null
});

var str = 'beep';
console.log( str.replace( obj, 'boop' ) );

defineProperty( obj, ReplaceSymbol, {
    'configurable': true,
    'value': replace
});
console.log( str.replace( obj, 'boop' ) );
