This example shows the most basic inheritance feature: classes inherit properties and methods from base classes. Youll notice the TypeScript keyword let and the string type declaration. Its so easy to see this one on packaging, posters, T-shirts, and more. Below are two invitation examples using a mix of brand fonts and a script font.
