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 fine.
Are there any other ways to loop through this?
for (var i in a_hashMap[i]) {
console.log('Key is: ' + i + '. Value is: ' + a_hashMap[i]);
}
I run into a problem where this outputs a bunch of undefined keys after the first key, when the array only contains one entry. I have a feeling it is because the code is within a loop which uses i, even though when I follow in debug it shouldn't be happening. I also cannot change i as the for loop seems to not understand the replaced var at all.
Anyone any ideas?
