Top 5 TypeScript Interview Questions
What is the difference between "any" and "unknown" types in TypeScript?
Answer: "any" represents any type in TypeScript, while "unknown" describes a style that's not known until runtime. "unknown" is a safer alternative to "any" because it forces developers to check the kind of a value before using it.
This question is essential in evaluating a developer's understanding of TypeScript's basic types and their differences. The candidate's answer should demonstrate that they understand the use cases for each type and can explain why "unknown" is generally considered safer than "any."
What is a decorator in TypeScript, and how is it used?
Answer: A decorator in TypeScript is a special declaration that can be attached to a class declaration, method, accessor, property, or parameter. It's used to modify or extend the behavior of the decorated element. Decorators are typically used in frameworks like Angular to add metadata to a class or component.
This query evaluates the developer's familiarity with advanced TypeScript features and how they're used in popular frameworks. The candidate's answer should demonstrate that they understand the role of decorators in modifying or extending the behavior of elements in a TypeScript application.
What is an interface in TypeScript, and how is it different from a class?
Answer: An interface in TypeScript is a contract describing an object's properties and methods. It's used to define the shape of a thing, but it doesn't provide an implementation. Conversely, a class is a blueprint for creating something that provides a definition and a performance.
This question assists in knowing a candidate's understanding of the basics of TypeScript and syntax. The candidate's answer should demonstrate that they understand the interfaces' purpose in describing an object's shape and the differences between interfaces and classes in TypeScript.
What is the difference between a namespace and a module in TypeScript?
Answer: A namespace in TypeScript is a way to organize code by grouping related classes, interfaces, functions, or variables under a single name. A module, on the other hand, is a way to organize code by grouping related code under a single file or directory. Modules are the recommended way to organize code in TypeScript.
This inquiry evaluates the developer's proficiency with how TypeScript organizes code and the best practices for doing so. The candidate's answer should demonstrate that they understand the differences between namespaces and modules and why modules are generally preferred for organizing code in TypeScript.
What is a type assertion in TypeScript, and how is it used?
Answer: A type assertion in TypeScript is a way to tell the compiler that a value has a specific type, even if the compiler can't infer it. It's used when a developer knows more about the value type than the compiler. Type assertions are performed using the "as" keyword or by enclosing the value in angle brackets "<>."
This query gauges a candidate's knowledge of TypeScript syntax and its type system. The candidate's answer should demonstrate that they understand the use cases for type assertions and how they tell the compiler the type of a value when it can't be inferred.
