What is spacing between lines or text?
Line spacing is the space between the lines of code. Most
programming languages ignore whitespace, which allows you to insert
blank lines in order to help separate blocks of code to make the
code more readable. However this is not strictly the same as line
spacing, which is normally defined by the typeface employed by your
code editor. Word-processing programs allow you to specify
different line spacings depending on whether an element is a
paragraph, a bullet point or some other construct. But programming
editors are typically plain-text editors and do not generally have
line-spacing characteristics, hence the need to insert blank
lines.
