The document discusses best practices for choosing clear and informative variable and function names in code. It recommends using specific words that describe the variable or function's purpose over cute or generic names. Names should be concrete rather than abstract, and extra context can be provided with prefixes or suffixes. The length of a name should be long enough to convey essential information.

It’s better to be clear and precise than to be cute.

4. Avoiding Generic Names
● The name retval doesn’t pack much information. Instead, use a name that
describes the variable’s value.
● The name tmp should be used only in cases when being short-lived and
temporary is the most important fact about that variable.
● Sometimes there are better iterator names than i, j, and k
