Creating custom types in Go has several advantages: Enhanced readability: Create domain-specific types to improve the readability and understandability of your code. Ensure data integrity: Implement data validation rules to ensure data accuracy and consistency. Encapsulate implementation details: hide internal implementation and simplify code maintenance and modification. Improve code reusability: Create reusable types that reduce code duplication and workload.
Advantages of creating custom types in Golang
Creating custom types in Go language is a very useful Technology that can greatly improve the readability, maintainability and reusability of code.
Advantages:
Practical case:
Let us illustrate the advantages of creating custom types through an example. Suppose we want to write a program that calculates the area and perimeter of a rectangle. When there is no custom type, we can write code like this:
1 2 3 4 5 6 7 8 9 10 |
|
Using custom types, we can further improve the readability and reusability of the code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
|
The above example shows How to create a Rectangle
custom type that encapsulates the length and width of a rectangle and provides Area
and Perimeter
methods to calculate the rectangle's area and perimeter. This is more expressive than the first example and easier to reuse.
