I see both type of coding style in use:

\newcommand{\hello}{Hello, World}

\newcommand\hello{Hello, World}

My question: Is there any situation where removing the braces around the command name being defined with \newcommand or \renewcommand would provide a result or behavior that is different from what it would if we do not remove the braces around the command?

yes (to the question in the title) no (to the question in the post) – David Carlisle May 27 '21 at 08:49

No difference, except if you forget the backslash or use numbers together with letters, but the code would be wrong anyway. – egreg May 27 '21 at 09:05

Does this answer your question? Why do people use braces around the control sequence in \newcommand? See also https://tex.stackexchange.com/q/1914/82917 – campa May 27 '21 at 09:46
