The Quest for the Ultimate TypeScript Developer: A Quirky Array of Questions
Let’s be real—no one wants an interview that feels like an inquisition, devoid of any spark. Interviews—they ought to ignite curiosity, not induce yawns! These 20 TypeScript Interview Questions? Oh, they’re here to set the room on fire.
The Basics: Do You Speak TypeScript?
- What’s the difference between TypeScript and JavaScript?
- Classic opening—like a good first line in chess. JavaScript, the wild child, spontaneous and free. TypeScript, its meticulous cousin, introducing order with type-checking. Are they well-versed in this delightful dichotomy?
- Explain the purpose of TypeScript’s type annotations.
- Oh yes, those nifty annotations—like whispering incantations over your code. These notations are the magic spells that promise sanity, predictability, and safety. Do they see the talismanic power in reducing runtime errors? If they do, we’re onto something!
- How do you declare variables in TypeScript?
- Variables—what’s their strategy? Are they all about the steadfast ‘const’, immovable like an ancient stone? Do they appreciate the flexibility of ‘let’ or the peculiar ghost of ‘var’ from JavaScript days of yore? It’s a dance of constants and variables.
- Can you explain Type Inference?
- Yes, yes—TypeScript with its subtle telepathy. This is the language’s sneaky mind-reading trick—infer what type you meant without you even spelling it out. Can they navigate this terrain without getting lost in ambiguity?
Hitting the Sweet Spot: Intermediate Understanding
- How do interfaces differ from types in TypeScript?
- Here comes the labyrinth—interfaces versus types. Different yet similar—like twins with distinct personalities. How do they dance between the two? Can they glide gracefully or are they stumbling through this quagmire?
- How can you enforce optional properties in an interface?
- Optional properties, marked by that curious little question mark (?). A symbol of flexibility—like a door left ajar, allowing possibilities. Are they comfortable wielding this choice-inducing magic?
- What are generics and how are they used in TypeScript?
- Generics! A universal potion, a shape-shifting spell allowing functions to work for anything and everything. Are they adept at concocting these potions—writing reusable, elegant, type-safe code that morphs to suit any occasion?
- When would you use an Enum in TypeScript?
- Enums—organized, sensible, categorizing the world into neat little sections. Are they wielding Enums like a taxonomist organizing species? The ability to use them correctly shows a mind geared towards structure.
Advanced Sorcery: The Ones Who Bend TypeScript to Their Will

- Decorators—oh, we’re talking magic here! Enhancers, transformers—bestowing powers and modifications on classes and methods. Do they know their way around these? The answer could determine if they’re a mere apprentice or a master sorcerer.
- Explain the difference between ‘unknown’ and ‘any’ types.
- ‘Unknown’ versus ‘any’—subtle as it is, it’s the difference between a contained explosion and a loose cannonball. ‘Any’—the chaos-bringer, uncontrollable, unpredictable. ‘Unknown’—the sensible barrier, needing inspection before use. Can they differentiate between these two worlds?
- How would you handle module imports in TypeScript?
- Imports and exports—like carefully planning your shopping list to avoid missing any ingredients. Do they get the ingredients just right, bringing modules together into a cohesive whole?

- What is ‘never’ type, and when do you use it?
- Ah, the ‘never’ type—representative of the void, the impossible. A type that cannot possibly exist, used to show what should ‘never’ be. Do they grasp this high-level trickery? A sign of a true conjurer.
Not Just Code: Evaluating Developer Experience & Collaboration

Teamwork & the Human Element: Developer Skills Beyond the Syntax
