let position = 0;

while (position < string.length) {� const codePoint = string.codePointAt(position);� position += codePoint <= 0xFFFF ? 1 : 2;� doSomething(position, codePoint);

// note: `position` === code unit offset�}

for (const symbol of string) {� const codePoint = symbol.codePointAt(0);� doSomething(codePoint);

// no `position` (i.e. code unit offset)�}

for (const codePoint of string.codePoints()) {� doSomething(codePoint);

// no `position`�}
