Types are optional in the programming languages I write most in. I like them, but I also like people can decide whether to use types or not.

The main programming languages I write are PHP and JavaScript.
|
||
|
|
|

|
|
Both offer types where, as well as declaring a parameter or property, you can define what type it is - whether it's a string, array, boolean, etc.
|

|
|
|

|
|
Adding types is optional.
|
||
|
|
|
||
|
|
You don't need to add types to your PHP code, and you can choose to write plain JavaScript instead of TypeScript.
|
||
|
|
|

|
Some people prefer simpler or cleaner code or less "visual debt".
|

I like the extra clarity that types add.
|
||
|
|
|
||
|
|
I like to be able to read some code and immediately know what types things should be.
|
||
|
|
|
||
|
|
I like the clearer errors and messages if a different type is given than was expected.
|
||
|
|
|
||
|
|
Tools like PHPStan know more about my code and give better recommendations than if I don't add types.
|
||
|
|
|
||
|
|
I like the better autocompletion I get when writing code that has types.
|
||
|
|
|

|
|
I like types, but I also like the flexibility of whether or not to add them and for Developers and development teams to make their own decisions based on their preferences.
