Is it bad to declare variables at the beginning of the code?

Question

Programming

I'm relatively new to programming (learning js). And I've got into the habit that when I'm practicing, doing some little To-Do web applications, I declare variables at the beginning of the code. But now I read that this is just a terrible habit. Do you think this is so?

Answer 1

For JS, it's quite normal. This is not a good practice for statically typed languages, but in JS it is quite normal.

Answer 2

Normal practice is to combine initialization and declaration of variables. At least the code reads better. You don't have to remember which variable you're assigning to and whether it overwrites previous data.
