papplyRight

Partially apply function arguments from the right.

Usage

var papplyRight = require( '@stdlib/utils/papply-right' );

papplyRight( fcn[, ...args] )

Partially applies function arguments from the right.

function say( text, name ) {
    return text + ', ' + name + '.';
}

var toSusan = papplyRight( say, 'Susan B. Anthony' );

var str = toSusan( 'Thank you' );
// returns 'Thank you, Susan B. Anthony.'

str = toSusan( 'Never forget' );
// returns 'Never forget, Susan B. Anthony.'

Notes

The implementation does not set the length of the returned function. Accordingly, the returned function length is always 0.
The evaluation context is always null.
The difference between this function and papply is the order in which arguments are applied. This function fixes the rightmost arguments.

Examples

var randu = require( '@stdlib/random/base/randu' );
var floor = require( '@stdlib/math/base/special/floor' );
var papplyRight = require( '@stdlib/utils/papply-right' );

var fcn;
var x;
var y;
var z;
var v;
var i;

function add( x, y, z, w, t, s ) {
    return x + y + z + w + t + s;
}

fcn = papplyRight( add, 5, 4, 3 );

for ( i = 0; i < 100; i++ ) {
    x = floor( randu() * 5 );
    y = floor( randu() * 10 );
    z = floor( randu() * 15 );
    v = fcn( x, y, z );
    console.log( '%d+%d+%d+5+4+3 = %d', x, y, z, v );
