Dealing with duplicate declaration warning for loop variables

Question

Consider the following code:

for (var i=0; i<100; i++) {
    // your code here
}
// some other code here
for (var i=0; i<500; i++) {
    // custom code her         


        

Answer 1

I tend the use the array built-in functions, such as map, filter and forEach, thus avoiding the issue altogether. This also automatically gives you scope loop bodies which is also quite useful.

If using those doesn't match the use case I usually resort to top declaration, simply so I can avoid the issues you mentioned.
