This is an arrow expression. It creates a function. There's nothing in the curly braces, so no code will execute. It's part of JavaScript, not React Native-related.

For example, you could write a function named myFunction like this:

var myFunction = (name) => {
    console.log("Hello, " + name);
}

See the MDN docs for more info: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions
