Loop through a 'Hashmap' in JavaScript

Question

I\'m using this method to make artificial \'hashmaps\' in javascript. All I am aiming for is key|value pairs, the actual run time is not important. The method below works fi

Answer 1

Do you mean

for (var i in a_hashmap) { // Or `let` if you're a language pedant :-)
   ...
}

i is undefined when the for-loop gets set up.
