forEachCodePoint

Usage

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

forEachCodePoint( str, clbk[, thisArg ] )

Invokes a function for each Unicode code point in a string.

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

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

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
};

forEachCodePoint( str, clbk, ctx );

var cnt = ctx.count;
// returns 2
