Usage

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

#### logEachMap( str\[, ...args], clbk\[, thisArg] )

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

`javascript
function add( a, b ) {
return a + b;
}

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

logEachMap( '%d + %d = %d', x, y, add );
// e.g., => '1 + 4 = 5\n2 + 5 = 7\n3 + 6 = 9\n'
`

The function accepts the following arguments:

- str: format string.
- args: input arrays _(optional)_.
- clbk: callback function.
- thisArg: callback execution context _(optional)_.

To set the callback execution context, provide a thisArg.

`javascript
function count( x, y ) {
this.count += 1;
return x + y;
}

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

var ctx = {
'count': 0
};

logEachMap( '%d + %d = %d', x, y, count, ctx );
// e.g., => '1 + 4 = 5\n2 + 5 = 7\n3 + 6 = 9\n'

var v = ctx.count;
// returns 3
`

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

`javascript
function multiply( x, y ) {
return x * y;
}

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

logEachMap( '%0.1f * %0.1f = %0.1f', x, y, multiply );
// e.g., => '1.0 0.5 = 0.5\n2.0 0.5 = 1.0\n3.0 * 0.5 = 1.5\n'
`

The callback function is provided the following arguments:

- arg0: current array element for the first broadcasted array.
- arg1: current array element for the second broadcasted array.
- ...argN: current array element for the nth broadcasted array.
- index: current element index.
- arrays: broadcasted arrays. If an argument was broadcasted, the corresponding array is a single-element generic array containing the original element.

The number of argX arguments is determined according to the number of provided args arguments. If no args are provided, the callback is invoked without any arguments.
