    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>

## Installation

<section class="usage">

## Usage

```javascript
var log = require( '@stdlib/console-log' );
```

#### log( \[data]\[,...args] )

Outputs a message to the debugger console.

```javascript
log( 'Hello, World!' );
```

If the first argument is a string, the argument is the primary message and may include zero or more substitution strings.

```javascript
log( 'Hello, %s!', 'World' );
```

## Notes

-   In general, prefer formatting with [`@stdlib/string-format`][@stdlib/string/format], as string substitution support is not consistent across JavaScript environments.

    ```javascript
    var format = require( '@stdlib/string-format' );

    log( format( '%s: %.2f', 'Foo', 3.14 ) );
    ```
