What’s Kotlin Design Pattern Used For?

A style guide is an important document for software developers and their teams. Their’s many benefits of a style guide, and many times it’s almost mandatory for some Android projects because theirs so many benefits of having a style.

When is a Style Guide Used?

A style guide can be used for an entire programming language. A personal style guide can be used for a single Android project or even an entire team. The style guides main goal is to create a path of familiarity when you program in the language.

Consistency

In Python a variable declaration would look like this, separate words would have _’s between them.

While Kotlin would use camel casing:

Within the programming language, it’s uncommon in kotlin to use underscores, and it’s uncommon in Python to use camelCasing. Having to use a naming convention creates a consistency within the language. Having consistencies makes the language easier to read, not wasting time learning a whole new naming convention. A project would be hard to read if a developer kept switching between camel casing, and using underscores.

Easy to Read

In a style guide, their will almost always be sections that will be dedicated to making the code look pretty! Like always having braces on if statements. These design patterns are usually not a personal opinion, one is going to be easier to read for the majority of the people. A style guide will have this dedicated section for making it pretty and it’s important to follow it exactly. Using those rules will allow others to read your code easier, faster, and result in fewer errors.

Errors

Without a design pattern, every piece of code would look different and result in more errors. Maybe you misread an if statement because one had braces and another didn’t. Easy mistake, but a costly one.
