Why is naming variables so hard?

He points out that many variables are just unnecessary, so it’s better to create them as an anonymous instead of having them locally with assigned names. New variables make the code longer because they need extra lines to be declared. And they make the code more complex because its reader has to remember more names.

What makes for a good or bad variable name?

A variable name should tell you concisely in words what the variable stands for. Your code will be read more times than it is written. Prioritize how easy your code is to read over than how quick it is to write.
