    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

```bash
npm install @stdlib/console-log-each
```

</section>

<section class="usage">

## Usage

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

#### logEach( str\[, ...args] )

Inserts array element values into a [format string][@stdlib/string/format] and prints the result.

```javascript
var x = [ 1, 2, 3 ];
var y = [ 4, 5, 6 ];

logEach( '%d < %d ', x, y );
// e.g., => '1 < 4\n2 < 5\n3 < 6\n'
```

If an interpolated argument is not an array-like object, the argument is broadcasted for each iteration.

```javascript
var x = [ 1, 2, 3 ];
var y = 0.5;

logEach( '%0.1f > %0.1f', x, y );
// e.g., => '1.0 > 0.5\n2.0 > 0.5\n3.0 > 0.5\n'
```

<!-- Package usage notes. Make sure to keep an empty line after the `section` element and another before the `/section` close. -->

<section class="notes">

## Notes

-   If the function is provided array-like objects of unequal lengths, the function throws an error.
-   The function supports array-like objects supporting the accessor protocol (e.g., [`Complex128Array`][@stdlib/array/complex128], [`Complex64Array`][@stdlib/array/complex64], etc).

## Examples

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

```javascript
var discreteUniform = require( '@stdlib/random-base-discrete-uniform' ).factory;
var naryFunction = require( '@stdlib/utils-nary-function' );
var filledBy = require( '@stdlib/array-filled-by' );
var map = require( '@stdlib/utils-map' );
var abs = require( '@stdlib/math-base-special-abs' );
var logEach = require( '@stdlib/console-log-each' );

var rand = discreteUniform( -50, 50 );
var x = filledBy( 10, 'float64', rand );

var y = map( x, naryFunction( abs, 1 ) );
logEach( 'abs(%d) = %d', x, y );
