Naming Convention Explained – Camel vs Pascal vs Kebab vs Snake Case
A naming convention is a pattern generally accepted as a suitable format for naming coding entities like variables, functions, and properties.
Why the Need for a Naming Convention?
Section titled “Why the Need for a Naming Convention?”Most computing languages do not allow using spaces to separate words when naming your code.
