Test Object Builders. Dependencies and Obscurity account for the three manifestations of complexity. Clean code is easy to maintain. This prevents problems that may occur when working withlegacy code, for example. The first one is an arrow function, with no colons and no return, while the other is a common function that uses colons and a return. With understandability comes readability .

Code reusability is a fundamental concept in software engineering that refers to the ability of code to be used multiple times without modification. Another way to document code is by using inline documentation. A variable name should always be self-explanatory. For example, you might often be working with a User object that contains all sorts of data about any given user.

On the other hand, example 2 is much more convoluted, with variables declared outside of any function and multiple if statements used to check if the code block has executed successfully. The commonality between these 3 camps is they all believed their choice and preferred programming language enabled them to write Clean Code!
