Access previous key/value in for-in loop
for-in-loop, for-loop, javascript, loops
Solution
No, there's no direct way. One workaround would be to use a `for` loop over `keys` instead of `for..in` and pick elements by their numeric index:
keys = Object.keys(myObj);
for(var i = 0; i < keys.length; i++) {
current = keys[i];
previous = keys[i - 1];
next = keys[i + 1];
...
}
Problem
I am new to javascript so please excuse me if its something obvious. Lets say I have a for-in loop as follows... ``` for( var key in myObj ){ alert("key :" + myObj[key] ); // accessing current key-value pair //how do I access previous element here? } ``` Is it possible to access previous or next key/value pair in for-in loop?
