Hi Vijay,  Thanks for reaching out! The additional space is there for better readability of our code. You don't strictly need it, from the compiling point of view. It is however, crucial in order to write clean code. Usually the more we code, the longer and more complex our code tends to get. So, it's important for it to be understandable. Especially because, often, we're not the only people looking and going through the code.  So, even though it's not a strictly necessary step, it's a highly recommended one!   Best,  Eli
