Argument Function

Create an argument function.

Usage

var argumentFunction = require( '@stdlib/utils/argument-function' );

argumentFunction( idx )

Returns a function which always returns an argument corresponding to a specified argument index.

var argn = argumentFunction( 1 );
// returns <Function>

var v = argn( 1.0, 2.0, 3.0 );
// returns 2.0

v = argn( 'a', 'b', 'c' );
// returns 'b'

If an argument function is provided fewer arguments than the specified argument index, an argument function returns undefined.

var argn = argumentFunction( 100 );
// returns <Function>

var v = argn( 1.0 );
// returns undefined

Notes

• Argument indices are zero-based.

Examples

var randu = require( '@stdlib/random/base/randu' );
var argumentFunction = require( '@stdlib/utils/argument-function' );

var argn;
var v;
var i;

argn = argumentFunction( 1 );
for ( i = 0; i < 10; i++ ) {
    v = argn( randu(), randu()*10.0, randu()*100.0 );
    console.log( v );
}
