In most code editors in programming, the line numbers are displayed in a column to the left of the code, and some other lines may be empty while the rest contain commands or syntax. Most line counts that are left when or during programming or coding help a lot. There are lots of reasons why they are left and how they assist most users in the field.
Below are the reasons:
EMPTY LINES
Empty lines could be left blank, this, is intensionally left blank to separate logical sections of codes, making it easier to read and understand.
LINE BREAKS
Also, line breaks. Some programming languages, for example, Python, use breaks to define the end statement or block of code. Meanwhile, the line number is still displayed, but the line
itself is empty.
CODE FOLDING
Another interesting aspect is that, mainly CODE FOLDING. As mentioned earlier, some code editors use code folding to collapse sections of syntaxes or code or commands. When a section is known to have collapsed, the line numbers may still be displayed but the corresponding lines of codes are hidden.
