Challenge: Print Numbers from 5 to 9

Task

Let's implement a while loop that outputs numbers from 5 to 9 to the console.


              
123456

            
let a = 5;

___ (a ___ ___) {
  console.log(___);
  ___++;
};
copy

The output should be:

python
  1. Set the condition toΒ a <= 9Β orΒ a < 10.
  2. Include the variableΒ aΒ within theΒ console.log()Β function.
  3. Increment the value ofΒ aΒ inside the loop.

              
123456

            
let a = 5;

while (a <= 9) {
  console.log(a);
  a++;
}
copy

Everything was clear?

How can we improve it?

Thanks for your feedback!
