Вопрос 36

A for...of loop processes a string containing one supplementary Unicode code point encoded as a surrogate pair. How many loop values represent that code point?

  1. Two, one for each code unit
  2. One, for the combined code pointПравильный ответ
  3. Zero, because it is not basic Unicode
  4. A runtime-dependent number

Объяснение

String iteration combines the surrogate pair into one Unicode code point, so one loop value represents it. Counting two would copy the code-unit behavior of length or bracket positions into a code-point iterator.
