Advanced Static Types in TypeScript
|
Learn how to write safer code with TypeScript’s advanced static types. Explore non-nullable types, control flow analysis, and type guards. Discover string enums, literal types, discriminated unions, and rest/spread operators. Also, understand dynamic property access and transformation functions. Enhance your TypeScript skills with this comprehensive course.
This course explores the capabilities of TypeScript’s type system and shows how to use advanced static types in practice. For example, you’ll learn how to write safer code by using non-nullable types and being explicit about
and
in the type system.
You’ll also see how the compiler analyzes control flow to determine the most specific type for a variable at any given location.
In addition to that, you’ll learn about the
modifier and the special
and
types. This course also inspects string enums, literal types, discriminated unions, and static types for the rest and spread operators.
Finally, you’ll see how to type dynamic property access using the
operator and how to create new types by applying transformation functions to existing ones.
