Starting from Scratch

Start with a feature, not a layout

• An app is actually a collection of features.
• Instead of starting with the shell, start with a piece of actual functionality.

Detail comes later

• In the earliest stages of designing a new feature, it’s important that you don’t get hung up making low-level decisions about things like typefaces, shadows, icons, etc.

Functions

Function Parameters

• Without explicit type information declared, TypeScript will consider the function parameters to be the any type, meaning the parameter’s type could be anything.
• TypeScript allows you to declare the type of function parameters with a type annotation.
