DO use forEach if you are only going to apply a function or a method to all the elements of an iterable.

Using forEach when you are only going to apply a function or method to all elements of an iterable is a good practice because it makes your code more terse.


for (final key in map.keys.toList()) {



NOTE: Replacing a for each statement with a forEach call may change the behavior in the case where there are side-effects on the iterable itself.

for (final v in myList) {
  foo().f(v); // This code invokes foo() many times.

myList.forEach(foo().f); // But this one invokes foo() just once.
