first
Returns the first item in an array. This is a convenience wrapper around index 0, useful in code that reads better as an operation on the collection itself. If the array is empty, the runtime result is undefined, even though the TypeScript declaration follows the array item type.
Usage
ts
const users = ['Ada', 'Linus', 'Grace'];
const firstUser = users.first();
// 'Ada'Returns
The first array item.
Type signature
ts
interface Array<T> {
first(): T;
}
