Code Inspection: 'for..in' is used instead of 'for..of'

Reports a usage of a for..in loop on an array. Suggests replacing it with a for..of loop.
for..of loops, which are introduced in ECMAScript 6, iterate over iterable objects. For arrays, this structure is preferable to for..in, because it works only with array values but not with array object's properties.

Suppress an inspection in the editor

  1. Position the caret at the highlighted line and press Alt+Enter or click the Intention action icon.

  2. Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
