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 );
