-With React Native, you don't use a special language or syntax for  defining styles. You just style your application using JavaScript. All of the core components accept a prop named `style`. The style names and values usually match how CSS works on the web, except names are written like `backgroundColor` instead of like `background-color`.

The style names and values usually match how CSS works on the web, except names are written using camel casing, e.g `backgroundColor` rather than `background-color`.
 
 The `style` prop can be a plain old JavaScript object. That's the simplest and what we usually use for example code. You can also pass an array of styles - the last style in the array has precedence, so you can use this to inherit styles.
