for-in Statement

The for-in statement is used to execute a loop for each element in a list. The body that follows the list can be either a single statement, or set of statements inside braces ( { and } ). This statement executes as follows:

  1. A variable is set to the first or next element of the list.
  2. The body executes. If a break statement is encountered in the body, the loop terminates.
  3. Steps 1 and 2 are repeated while there are elements left in the list or until a break statement is encountered.

When the loop is complete, the variable contains the last value assigned to it.

for variable in list body;
for name in {"one", "two", "three"}

The statement prints each element in the list.
