What am I doing wrong ?

In the Ruby challenge " Using a while loop, increment the value of the variable i as long as it remains less than 5"

i = 0 while i < 5 i =+ 1 end

It says "Your code took too long to run" What's wrong with my answer?

Thanks

You've got =+ instead of +=

Add AND assignment operator, adds right operand to the left operand and assign the result to left operand. c += a is equivalent to c = c + a

Correct answer:

i = 0

while i < 5
  i += 1
end

You mistyped the += operator. Your code would be more readable and you may pick up on these types of mistakes easier if you format and indent your code as well.
