forEachCodePointRight

Invokes a function for each Unicode code point in a string, iterating from right to left.

Usage

var forEachCodePointRight = require( '@stdlib/string/base/for-each-code-point-right' );

forEachCodePointRight( str, clbk[, thisArg ] )

Invokes a function for each Unicode code point in a string, iterating from right to left.

function log( value, index ) {
    console.log( '%d: %s', index, value );
}

forEachCodePointRight( 'Beep!', log );
/* =>
    4: !
    3: p
    2: e
    1: e
    0: B
*/

The invoked function is provided three arguments:

value: Unicode code point.
index: starting Unicode code point index.
str: input string.

To set the function execution context, provide a thisArg.

function clbk() {
    this.count += 1;
}

var str = '👉🏿';

var ctx = {
    'count': 0
};

forEachCodePointRight( str, clbk, ctx );

var cnt = ctx.count;
// returns 2

Examples

var forEachCodePointRight = require( '@stdlib/string/base/for-each-code-point-right' );

function log( value, index ) {
    console.log( '%d: %s', index, value );
}

forEachCodePointRight( 'presidential election', log );
forEachCodePointRight( 'Iñtërnâtiônàlizætiøn', log );
forEachCodePointRight( '🌷🍕', log );
forEachCodePointRight( '\uD834\uDD1E', log );
