Concatenation

I realize we learned concatenation but I am having trouble seeing how it worked in the first for loop example. He created a variable called "text," then ran the loop and out came "1 2 3 4". I feel like that part was glossed over a bit. Someone, please explain that, because that has been what has been stumping me more than the actual loops.

I actually got the answer off a freecodecamp forum. I found that the empty variable is expected to be a string.

You can think of concatenation as "glue", so it just sticks two strings together to make one longer one.

When the first string is empty, concatenating it does the same thing as assigning it with the second value.
