Var reassigned without keyword var

Tell us what’s happening:
In one of the previous exercise it was told to not declare variables without the keyword var. Reassigning it without the keyword is fine, is it?

Your code so far

// Example
var changed = 0;

function change(num) {
  return (num + 5) / 3;

changed = change(10);

// Setup
var processed = 0;

function processArg(num) {
  return (num + 3) / 5;

// Only change code below this line
var processed = processArg(7);

Link to the challenge:

Yes, that is why you should really write:

processed = processArg(7);

Thank you for replying.
