Characteristics of a Good Function

◀ How to Write a Function Efficiently▶ Code Size of a Function Amazon Let’s first discuss characteristics of a good function. The code that achieves some purpose can be written in so many different ways; so how do we judge whether a function is well written?

To answer this question let’s look at the core properties of a function: code size, efficiency, memory footprint, reliability, and generality. In general a good function should have the following properties:

• short code size
• high efficiency
• low memory footprint
• high reliability
• and high generality

Below we’ll look at each property and explain why they are true!
