Note that the function pickCard(x): any piece is not part of the overload list, so it only has two overloads: one that takes an object and one that takes a number.Ĭalling pickCard with any other parameter types would cause an error. If it finds a match, it picks this overload as the correct overload.įor this reason, it’s customary to order overloads from most specific to least specific. It looks at the overload list and, proceeding with the first overload, attempts to call the function with the provided parameters. In order for the compiler to pick the correct type check, it follows a similar process to the underlying JavaScript. With this change, the overloads now give us type checked calls to the pickCard function. Some benefits of an evening of Ten Minute Plays. For Forensics, the Additional Venue fee is waived.

This makes it a very powerful and flexible feature, but it comes at the cost of always having to know about the context that a function is executing in. Ages of the actors: Late twenties and up. In JavaScript, this is a variable that’s set when a function is called. Yehuda’s article explains the inner workings of this very well, so we’ll just cover the basics here. If you need to learn how this works in JavaScript, though, first read Yehuda Katz’s Understanding JavaScript Function Invocation and “this”. Since TypeScript is a superset of JavaScript, TypeScript developers also need to learn how to use this and how to spot when it’s not being used correctly.įortunately, TypeScript lets you catch incorrect uses of this with a couple of techniques. Learning how to use this in JavaScript is something of a rite of passage. rest : string ) => string = buildName Try this
