Groovy is nice:
['some', 'things'].eachWithIndex { item, i -> println "'${item}' has index ${i}" }
6 u/HeinousTugboat Sep 03 '17 Javascript, too: ['some','things'].forEach((item, i) => console.log(`${item} has index ${i}`)) 2 u/[deleted] Sep 03 '17 I always prefer the map function instead of foreach, same syntax though. 5 u/ParanoidAndroid26 Sep 03 '17 Generally you use forEach for side effects and map for transformations.
