This TS naming convention is weird

Here are my top 4 rules for how to name your types in TypeScript.

Never pluralize: Unless your type is an array type, you should make it singular - even if it's a union of members.

Casing: Choose a different casing between your values and your types. This helps stop syntax highlighting getting confused.

Type Parameters: prefix your type arguments with T. If you've got only one type argument, you can use T. Otherwise, be more descriptive with your parameter names.

Avoid Unnecessary Prefixes: Prefixes like IUser and TOrganization might feel useful, but they're mostly just holdovers from the Java days.
